Has anyone else had poor results with the Generic Lexapro, Escitalopram? This is the third time I'm trying to go on the generic because it's so much cheaper than the brand name. I want it to work, but it just isn't the same. I don't feel well-dull and head achey, and my mood is down. I want to give it plenty of time, but it's been about five weeks and I'm getting discouraged.
