I've been taking 12.5 mg of Paxil for a month now for anxiety. I just refilled a script, but haven't picked it up. I have an Dr appointment in two weeks. I was thinking of asking for different meds because I think it's causing me to gain weight, which I am extremely concerned about. What will happed if I stop taking it right now? I've already missed 2 doses. Will I go through withdrawal symptoms, or not because of the short period of usage. Also, if I wish to switch meds, would it help to keep taking the paxil to bridge between the two, or not? Are there any good anxiety drugs that definitely do not cause weight gain? What about drugs that aren't SSRI's?
