What vitamin or pill can I take to speed up metabolism to help with weight loss since I think my celexa (citalopram) is working against my weight loss?

Warning: Info only! I'm not recommending this - but it does seem reasonable and might help you in some way. http://www.theroadback.org/weight_loss.aspx an interesting fact is that the digestive tract has more serotonin receptors than the brain. That's a reason for weight ; stomach side effects so many have. Consider psychotherapy as a bridge to reduce med needs. You learn skills w/out side effects. Best!
