I started on escitalopram (Lexapro) 10mg to treat some anger issues and felt like it was working quite well but still had a little edge. My Dr. recommended upping dose to 15 and seeing how it goes. After taking it for a few weeks it has helped tremendously with my issues but I am having quite a bit of anxiety and what feels like elevated heart rate. I am also having problems going to sleep even when I am exhausted. I know these are known side effects, but I had none of this when I started taking 10 in the first place. Realistically how long should I wait to consider moving my dose back down?
