I was originally prescribed the drug for severe depression. It sure helped me, allright, a little too much! It put me into a manic state, which got higher and higher with each day I was on it. The mania made me feel invincible, so energetic, non-stop talking/ moving/ laughing. It felt great, especially after being so depressed for so long. It made me feel like I can accomplish anything. I would get up early and not even be tired from lack of sleep. I would go out and exercise like running (like a maniac lol) without hardly getting tired.
The problem is that it just made me too crazy and I was bound to get into trouble with it. So they took me off it and it faded away quickly. But I thought, what if I just took a smaller dose than they gave me? Wouldn't it energize me without making me manic? So a couple years later (now) I decided to find out. So I took some more and sure enough this is just what it did. I felt happy, confident, energetic, optimistic, etc. It was great.
But after a while it seemed like it was fading away, like it was all a placebo or the effect was just in my mind. So I raised the dose but still no effect. So I really don't know what to think of the stuff but I'm now going off it to see if I feel any different. Another person I know who took it for depression also said that it made him manic.
