Yeah, Sandi-- what dose did you start with? I felt strange for the first few days on Lexapro. I started at 10 mg, half the standard dose. But after about a week, it kicked in, and I felt a tremendous difference-- startling, really (in a good way). I can't tell you how much this drug has improved my mental and emotional clarity. After another four months or so, I upped the dose to 20 mg (under the direction of a psychiatrist).
You can certainly get off of it... but you may not know what it can do for you unless you give it a fair trial. Also I take mine around dinner time. I don't take anything on an empty stomach. If you have an ulcer, IMHO this would be particularly important.
