I'm still taking the Lexapro, too, been on it for 3 wks, and although I was speedy the first 10 days or so, that didn't last and in the last few days I feel a little depressed, but not bad at all. My doc didn't say to increase it, I guess when I go back we'll discuss that. But when I've had to increase other meds, like Welbrutrin, I have gotten the speedy effect as well as some increased anx for a few days to a week. I think that's pretty normal for these kinds of meds. Afterall, we experience the same symptoms when we start taking them, it's only natural to assume that an increase would produce similar symptoms. Good luck and stick with it and see what happens.
