Addiction - Sibutramine help

[chickchick]

Yeah I know this a drugs forum but I want help with something that i'm having trouble coming off.

I'm taking Sibutramine as a diet aid (orally). I believe it has a simaler chemical structure to amphetamine which is why I posted here. It's basically making me bad, I get stressed and easily anooyed on it. I grind my teeth all the time on it. I feel wired but knackered all the time. Sleep problems aswell. So is this normal or am I just more sensitive to it? (I do seem to be sensitive to anything I take) And how the hell do I come off it? I had come off for a week or 2 but found myself going back on when I got depressed about something. It stops me getting that empty feeling in my belly which I think is the main thing I like about it.

Have lost all the weight I planned to loose so no real need to stay on it unless I get neurotic and feel I need to loose more and more.

Help!
