Krea-
have they checked your thyroid recently.....I found out that was part of my problem. I too take lexapro, and i think it goes in shifts of working, because sometimes it works great, and other times I feel like it doesn't do a thing.
If you want to you can always pm me. I check the site generally once a day if not more.

Hope life turns arround
