This is a hard one. Going back on celexa and tapering slowly may not work but is worth a try. Some people take 8 or more weeks to stabalize. Then you can do a slow taper. I suggest that since you're already three weeks into the RI that you give it at least five more weeks.

If you decide to just stay off it's really a crap shoot. Sometimes the wd symptoms pass in a few weeks but for others (like me) they can last for years. I had the kindling effect and now wish I'd given th RI more time.

You said you'd been on several ssris. Why did you keep changing? How long had you been on the celexa? Were you having trouble with the drug before you decided to quit? Are you taking any other psychotropic drugs at this time? Answering these questions will help us to guide you.
