Hey bro, glad to be here and glad to help. Provigil, drug name modafinil, is something I have no personal experience with. I'll be honest, if ever there was a time that I was tempted to take something like that, it would be now, as I enter the later stages of a diet, when my days are very long and my mind is turning into jello. I've heard of it referred to as the "new speed", helping people get a mental edge while not having all the side effects of amphetamine. If it were taken once in a great while, I'm sure it wouldn't pose any problems. Then again, that probably goes for a lot of things. The thing that scares me, is that I know there is no free lunch out there. Anything we take or do comes at a price. I wouldn't use it as a preworkout. I'm certain of that. Reason being, training is something I'm going to do every day and whatever PWO I use, it's going to be something I use every day. Provigil is something I would save for a more less regular occasion, if any at all
