Ew. I tried that stuff a few times and it was godawful.
I'll stick to coffee, thanks.
I've also had prescriptions for ritalin and wellbutrin. Ritalin on its own wasn't bad. It made me grouchy, tho. I took it for school and I was a little worried I'd end up getting arrested for fighting. I didn't bother with it. I tried selling the shit, but I've always been a lousy dope dealer. lol
The wellbutrin combo made my focus even worse than normal so I stopped taking it as well.
