please tell me about the anti depressant bupropion, my doctor is going to put me on this maybe but wanted me to research it also, I have gotten real depressed I am 69 yrs old and have a bad back, have knee pain & I have gained up to 154lb and it really makes things worse because of the weight I have put on, someone told me to research this drug it helped the depression plus would help in loosing weight. My question is will it do this, and what are the side effects? what do u think?
