I was recently switched from celexa to wellbutrin, and the side effects are awful. I feel loopy, can't focus, not motivated, angry, overwhelmed. I want to stop taking wellbutrin, and eventually would like to get off all meds. So what will/could happen if I stop taking my medication? Before the celexa and wellbutrin I was taking prozac for almost 10 years and NEVER had any side effects. Can I go backwards and get back on prozac?
