I take Provigil every morning around 8. I'm only taking 100 mg. per day for the past 1.5 years. Around 4pm, I'm exhausted. I would welcome an answer to this, as I can't find it in all of the sites I've looked... Thank you!
How long (hours) does Provigil last during the day?

I just started taking provigil for extreme fatigue. I take 200mg around 6am and then take another 100mg around 2pm. This seems to get me through the day. You might want to talk to your doctor about taking a stronger dose or taking two 100mg doses a day.
I, too, find taking a divided dose during the day helpful in controlling fatigue. I, also, take 200 mg at 6:00 a.m. and 100 mg at 2:00 p.m. Please note, my doctor and I experimented with several doses before arriving at this one. More importantly Provigil may interfere with sleep if taken too close to bedtime.
