For those that take Provigil, what is your dose? I just started taking this recently. Doc gave me a sample pack and said start with one pill and keep adding one more until it works.

Also, do you have to take it more than once throughout the day or is it supposed to keep you alert from morning until evening?

I haven't been on it long enough to decide if it's doing much good. So far, it seems to start out great in the morning and then fizzle out.

Thanks,
