I pretty much posted the same thing a few days ago,only I take celexa.Went off it and then back on,and had horrible anxiety for over a month! Just the past 2 days I am feeling abit better,I also had to increase the dosage(per doc's advice) as the former dose wasnt' doing the job anymore...I think maybe when you go off,you become abit resistant when returning to the same med,so a higher dose is more effective.
Good luck!
