Hi...personally, I would discuss this with your doctor as Lexapro and other SSRI's 'poop out' after extended use and sometimes the dosage has to be increased, or you might have to switch to another medication. I had similar experiences after being on it for two years, and finally just weaned off it because of the symptoms of it not working anymore were just too much for me to handle. I am not suggesting that this is definetley your problem...that would be up to your doctor. But I can relate to how you feel. I did not having any yellowing of the skin, however. Shakiness, light headness, palpataions and brain shocks. Best to be checked out!
Does Buspar work if it is taken every day! I am currently on ativan because my a/p is so severe!!!
