I seem to have slipped back. I suffer from health anxiety with scary thoughts that I can sometimes rationalize away, but then they creep back in quickly from another angle. Have been coping on my own for quite a few years. Quite a few years ago I was on Lexapro. It helped a LOT at first, but then I noticed I still worried, just a little less, but had also gained 40 lbs. It was terrible getting off. Now I'm at an "acute" stage again. I've noticed the Prozac has been giving me some better days, but the last two are almost the same. The only difference is that the thoughts are causing less real panic, but are still obsessive-like. Oh, I'm on 20 mg. I will keep going but how long?
