I've just ended day 3 of my Provigil trial.
Epic fail.
It's like irritability, fatigue, brain fog, flat affect, and OCD all rolled together in pill form, with no beneficial properties whatsoever. I'd think the pharmacy gave me the wrong stuff if the pills didn't have "PROVIGIL" stamped on them. There's no alertness, no wakefulness, no focus, no pep, no energy - just nasty mental side effects for hours and hours, long after any other stimulant would have worn off.
