I've been prescribed 50mg of Sertraline for anxiety (panic attacks, agoraphobia). I started with 1/4 of a pill for a few days then 1/2 and am now taking 3/4 but have increasingly felt worse. I'm 2 weeks in and feel much more anxious, tinnitus seems worse, bad sleep ...and not myself really. I don't want to keep going if it's going to get worse. I'm worrying it just won't work for me - Did anyone else stop or wean themselves off?
