Twink, it is the same as Provigil, I think. Some people have to take it very early in the am when they wake, to go to work. And not after the noon hour.

I took 100 mg in the am, and 100 mg around 12 noon, and then 100 mg at 2pm. I took Provigil, 300 mg is tops. They say 400 is okay but no more benefit than the total of 300 mg. When it stopped working I stopped it on the weekends and took it on Monday again.

I think I could take it at dinner and still konk out after an 8 hour work day and drive to and from work.

I think Nuvigil is the same dosing. If you find it too strong, maybe you don't need it? Or cut it in half or a quarter.

Better yet, call the prescribing doctor and explain.
