Been taking 50mg of sertraline daily for just over two months. My anxiety got better initially for the first month or so. In the last two weeks I’m getting racing heart etc and all the symptoms I used to get are returning. Spoke to the gp and they suggested a higher dose but now this has happened I am sceptical about whether it is sensible to increase? Surely the fact I was less anxious and now it’s back just suggests the medication isn’t working or have I just got used to it? I’d be grateful for any thoughts on this, I’m so disappointed as I really thought I was getting on top of my anxiety.
