I recently tried Zispin in an attempt to help my social anxiety and lasted only 4 days which says a lot about the experience I had on it. This drug is the stuff of nightmares (ironic seeing the major side effect is drowsiness). I have never felt so drowsy in all my life, in fact this should probly be remarketed as a sleeping tablet as that is all it seems to make you feel. The other major side effect is severe anxiety (my doctor prescribed this to help me feel less anxious). I've never felt so depressed and nervous in all my life, it was 4 days of a living nighmare. I stoppedtaking it last night and went back to my previous one efexor. I feel great today and glad to be off it.
