One hour before work is the labeled clock
US SWSD language commonly cites 200 mg one hour before the shift. This domain still locks 100 mg in public copy. Prescribers may start lower. The clock is the interaction with the roster: dose for the work block, not for breakfast on a rest day.
A rest-day 100 mg stolen from habit is how people lie awake through the only recovery sleep they had. That is a schedule pair, then an enzyme pair if they also take a steroidal contraceptive every calendar morning.
Driving home after a 12-hour night plus leftover drug is a safety pair with the road, not with CYP. If you cannot stay in lane, you do not 'need more 100 mg.' You need sleep or a work change.
Roster scrap for 100 mg nights
Write diagnosis, shift start, swallow time, rest-day rule, contraceptive method, inducers, hypnotics, last BP. SWSD omits rest days. Narcolepsy usually does not.
Four work nights a week still induce. Backup contraception does not pause on Tuesday. The extra month after a full stop does not follow the locker.
A second 100 mg at 03:00 is not labeled catch-up. If you cannot stay in lane, stop driving. Ceiling talk is clinic math, not a haul-road double.
Rifampin weeks steal wake and wreck the pill. Call both clinics. Do not add a black-market 200 mg foil.
Zopiclone at 09:00 plus 100 mg at 19:00 is a fall stack if clocks overlap. Do not add alcohol as a third hypnotic. Opioid nights add respiratory risk.
Enzyme depth: wake orbit. Parent: modafinil orbit. 112 for rash, chest pain, or unsafe driving.
Zopiclone in the morning, 100 mg at night
A hypnotic to force day sleep plus a wake drug for the night is a common clinic pair. It is also a fall and confusion stack if clocks slip.
Do not add a leftover benzodiazepine because the 100 mg 'felt weak' at 03:00.
Opioid night shifts add respiratory depression risk to any sedative. List them.
Roster pairs that still induce
SWSD labeling times modafinil about one hour before the night block. Rest days omit the tablet. This domain locks 100 mg. US text often cites 200 mg. Follow the bag.
A rest-day 100 mg stolen from habit wrecks recovery sleep. Rotating shifts do not pause induction. Backup contraception stays every calendar day even when the locker is dark.
A day-shift 100 mg at 06:00 and a night-shift 100 mg at 19:00 are different drugs in practice. Do not double on overlap Wednesday. Second 100 mg at 03:00 is not labeled catch-up. If you cannot stay in lane, stop driving.
Beer at 09:00 after a night block is still a stack. Caffeine at 05:00 to help the 100 mg invents tremor. Modest BP and pulse rises happen. Chest pain is 112.
Zopiclone at 09:00 plus 100 mg at 19:00 is a common pair and a fall stack if clocks slip. Do not add a leftover benzodiazepine because 100 mg felt weak at 03:00. Opioid nights add respiratory risk to any sedative.
Rifampin or carbamazepine steal modafinil and wreck the pill. Two inducers are not a locker-room puzzle. HIV cards vary. Bring them.
Narcolepsy usually keeps a daily morning rhythm. SWSD omits rest days. Mixing calendars is how partners fight about weekend crashing. Cataplexy needs another class.
Do not copy a roommate's 200 mg SWSD plan onto a 100 mg narcolepsy chart.
Enzyme rows: wake orbit. Parent: modafinil orbit.
Write diagnosis, shift start, swallow time, rest-day rule, contraceptive method, inducers, hypnotics, last BP.
Psychiatric activation belongs with rash in the urgent bucket.
[email protected] for sources. 112 for rash, chest pain, or unsafe driving.
Rifampin weeks wreck both wake and the pill
A new rifampin or carbamazepine course can steal modafinil and also wreck hormonal contraception on its own. Two inducers are not a puzzle for the locker room.
Sleepiness returning mid-antibiotic week is a pairing, not proof the 100 mg 'expired.'
HIV regimens vary. Bring the card.
A second 100 mg at 03:00 is not labeled catch-up
Ceiling talk is clinic math, often toward 400 mg/day in some indications, not a roadside double.
If you cannot stay in lane, you do not need more 100 mg. You need sleep or a work change.
Driving home after a 12-hour night plus leftover drug is a safety pair with the road.
Do not copy a roommate's 200 mg SWSD plan onto a 100 mg narcolepsy chart.
Modest rises, loud coffee
Modafinil can nudge blood pressure and heart rate. Night dehydration plus 100 mg plus interval training after shift is a palpitations story.
Chest pain is 112, not a dose tweak.
Psychiatric activation belongs in the same urgent bucket as a spreading rash.
Zopiclone at 09:00 after 100 mg nights
A hypnotic to force day sleep plus a wake drug for the night is a common clinic pair.
It is also a fall and confusion stack if clocks slip.
Do not add a leftover benzodiazepine because the 100 mg felt weak at 03:00.
Opioid night shifts add respiratory depression risk to any sedative.
Roster versus 100 mg
US SWSD language commonly cites 200 mg one hour before the shift. This domain locks 100 mg in public copy. Prescribers may start lower.
Dose for the work block, not for breakfast on a rest day. A rest-day 100 mg stolen from habit wrecks the only recovery sleep.
Rotating shifts do not pause induction. Backup contraception stays every calendar day.
A day-shift 100 mg at 06:00 and a night-shift 100 mg at 19:00 are different drugs in practice. Do not double on overlap Wednesday.
Second 100 mg at 03:00 is not labeled catch-up. If unsafe, stop driving.
Beer at 09:00 after a night block is still a stack. Count caffeine at 05:00 too.
Rest-day rules next to 100 mg nights
SWSD usually omits rest-day swallows. Narcolepsy usually does not. Write which diagnosis owns the 100 mg so a night-off does not become a mystery extra tablet.
Four work nights still induce. Backup contraception does not take Tuesday off. The extra month after a full stop follows the last swallow, not the locker roster.
A 03:00 second 100 mg is not a labeled catch-up. If you cannot stay in lane, stop driving. Ceiling talk is clinic math.
Rotating shifts do not pause induction
Three on, two off, 100 mg only on work nights still induces while the drug is in play. The extra month after a full stop still applies. A messy roster is not a loophole.
People forget backup on rest days because they 'did not take the wake pill.' Hormone exposure still saw the last doses.
Implants and pills both need a named plan. See the enzyme page for the one-month language.
Diagnosis owns the calendar
Do not copy a roommate's 200 mg SWSD plan onto a 100 mg narcolepsy chart.
Enzyme depth: wake orbit. Parent: modafinil orbit.
Psychiatric activation belongs in the same urgent bucket as a spreading rash.
Write shift start, swallow time, rest-day rule, contraceptive method, inducers, hypnotics, last BP.
[email protected] for sources. 112 for rash, chest pain, or unsafe driving.
This desk publishes charts. It does not write your roster.
Daily versus pre-shift is a diagnosis pair
Narcolepsy usually keeps a daily morning rhythm. SWSD usually omits rest days. Mixing the two calendars is how partners fight about 'weekend crashing.'
Do not copy a roommate's 200 mg SWSD plan onto a 100 mg narcolepsy chart.
Cataplexy still needs a different drug class.
Beer at 09:00 is still a stack
Night workers drink at breakfast time. Alcohol plus residual modafinil plus sleep debt is how near-misses happen on the Ring Road.
It is not a CYP table row. It is still a pairing you should write down.
Caffeine at 05:00 to 'help the 100 mg' invents tremor. Count it.

Get the diagnosis straight before anyone raises milligrams.
