I had a very difficult time stopping Lexapro. The first time I tried to stop cold turkey off of 10 and the withdrawals were so bad I had to go back on-- just like you, within a couple hrs. of taking just one pill I felt better.

The second time I stopped cold turkey for a about a week, but then I couldn't take it anymore. My pdoc had me cutting the 5mg in half (sort of difficult to do) and taking 2.5mg every other day. This really helped to ease the withdrawals. It took a litlte over 3 weeks for the symptoms to dissipate.

I wish I knew, beforehand, how difficult it would be to go off. I never would have started it in the first place b/c the med wasn't even a help to me.
