Hi I've just started sertraline (was on it for 8years) but came off 3 years ago to have a break. Any way my anxiety is so bad I've had to start again but I don't remember all these side effects... Please tell me it's normal, crazily heightened anxiety & red hot poker burning through my stomach pelvic area & in my feet & back. I'm only on 25mg & this is just taking 1 tablet last night. Dr's say push through it'll be worth it but it's making my already high anxiety unbearable.
