I took Citalopram (Celexa?) for 2 months (prescribed by neuro) and felt no different and was sleeping WAY too much and planned to quit. Internist prescribed Fluoxetine (Prozac?) and I did one day switch with no ill effects about 6 weeks ago. I don't think it's doing one bit of good either.
Oh, how I wish there were a magic pill somewhere ~sigh~
