That sucks SadDucky. Day 5 is still early though. If you don't start feeling better soon you can always give your doctor a call. You may just need a different pill. Some people have to try a few different brands before they find one that works. I've been on mine for almost a year now, and my doctor is wanting to start weaning me off 'em. I'd love to not have to take them anymore but I'm so nervous about the whole process. I'm worried the anxiety will come back with a vengeance.
Whatever happens just hang in there, and don't give up. Find what works.
