Wellbutrin is the same ingredient in zyban, i took this 5 years ago in order to quit smoking (i quit anyway 3 years ago, cold turkey) It Did not work, to say the least.
I spent the whole day wide eyed, paranoid, quick to anger, breathing problems, suicidal thoughts, numb skin,i wasnt able to wrestle up a feeling of hope, at all. I spent most of the night crying that i could not find a SOCK!
it took me a few days to shake the depression, then i did some internet research and found cases of ACTUAL suicides that are linked to the use of zyban.
I think it rewires the brain quite well for some people but severely messes up the happiness of the people who never really needed and antidepressant, or misdiagnosed patients, its scary stuff
