I tapered off Effexor 150 mg, but after being off for a couple of weeks I became completely emotional, either crying or fist-clenching stressed. Oh, and also having insomnia where I couldn't sleep at all. I had stopped taking Effexor because it was increasing my eye pressure. My doctor put me on 50 mg of Quetiapine and now I am so tired, still crying or stressing and feel completely out of it. I can't take this, and I can't get in to see the doctor for a month. Do you think I could just start back taking the Effexor that I have left over in the cabinet?
