I’ve gained over 20lbs in almost two years on 20mg of Citalopram despite not changing diet or activity levels, and am finding it really hard to lose any of it. My GP has suggested switching to Sertraline - saying that different drugs affect people in different ways so it’s hard to know if it would make any difference/make it worse/better. In other ways Citalopram has helped me a lot but the weight is making me miserable - would you try the switch? Any experience with Sertraline vs Citalopram?
