... noticing weight loss? I'm also on Celexa 20 mg but makes me feel palpitations and a bit jittery so I'm going to talk with my doc to put me back on 10 mg, in the past I gained weight with the meds I was given more then 3 years ago( can't remember the name) and I want to lose it back to my regular weight and how much weight does a person usually lose being on it for a couple weeks or months?
