Hi , I took 5 mg lexapro for 4 weeks then 10 mg for 8 weeks and 15mg for for 4 weeks , I'm now on week 4 of 20mg and while I'm starting to feel a bit better I'm still not feeling great , I'm getting very worried that lexapro is not going to work for me as I feel I have worked my way up through the doses without any success yet . How long more should I wait for it to work ? Any insight would be much appreciated.
