Yeah that doesn't sound good. I wouldn't continue with that. Especially at only 20mg. I was on 180mg and had a couple of bad days of withdrawal but I don't think dropping 20mgs will mess you up any more than being on it already has. Do talk to your doctor first but really those are totally intolerable side effects especially on such a low dose and after four months. You gave it a good shot but sometimes it's just not worth it.
