I took this for a while years ago.
The first week or so was rough--insomnia and anxiety all over the place! My body adjusted quickly and it also helped me quit smoking! After a week on it I just didn't want to smoke cigarettes anymore. It's marketed as zyban for smoking cessation. I noticed antidepressant effects in about 3 weeks. It wasn't a super happy YAY feeling, it was a subtle okayness that stayed with me. But I had to switch medications because I couldn't afford it.
Good luck
