Yeah, I've taken them, and its not something you should be getting yourself hooked on. I don't know how many I'd take, but I really didn't want to be awake, just wanted to be out of it, didnt want things to be so damn clear. Couldn't eat while on it, wanted to sleep but couldn't, my body felt soooo heavy.
You should stop, but you know, it's your life.
