Only because you asked for my personal experience: Prozac has been the best med for me with the least side effects. It did not completely stop my anxiety or help my depression, but it stopped the panic attacks. At the least is put a 'cap' on how high my anxiety got. My anxiety persisted, but it was manageable.

No weight gain or other side effects aside from temporary difficulty sleeping after dose increases.

Lexapro and Effexor are the only other SSRI and SNRI I have tried, and they both caused weight gain (from 130lbs to 170/180.) Lex made me incredibly lethargic. Effexor caused dizziness, restlessness, palpitations ... really, the whole gamut!!

YMMV The only thing you can do is try them for yourself and judge off of your own experience
