I have been taking 50mg of sertraline for anxiety for 16 days and the side effects are still really bad. Sweating, hot flushes, headaches, nausea, waves of anxiety and panic, running to the loo and generally feeling awful. The doctor doesn't know if this will settle or if I have Serotonin Toxicity so they are unsure if to take me off them. It seems a shame to be three weeks in and to have to now try something new. I have never felt so bad. Has anyone had a similar experience??
