okay so ive been getting very lightheaded for a long time now about 5 months almost and it started getting a lot better or at least the derealization was, but now starting the past 2 days its coming back really badly and today my doctor prescribed me paxil 10mg once a day. i just took my first pill about an hour ago. has anyone taken paxil before? or know anything about it? how long does it take to kick in? anything information on paxil would be a ton of help. thank you.
