deltreefitness said:I've taken Provigal as well. It's definitely not a wonder drug. It keeps me awake but I still feel like shit if I stay up longer than 12-20 hours. It also has some side-effects similar to typical stimulats like anxiety and crash. It also looses it effectiveness after a while (why I quit). Tolerance raises quickly.
I would assume that you were using it outside of necessary cortical activation through hypocretin/orexin receptors. For some people with cataplectic symptoms and clinical manifestations of intense, lengthy, and quick onset REM periods, it is a miracle drug.
