I started Lexapro about 2 1/2 months ago and have not had any bad side effects from it. I was feeling the depression coming on around the Holiday's and I didn't want to do anything or even get out of bed. I was BLAH!
It took about 4 weeks before I noticed a change in my depression and now I feel better. It's not a cure all but it has really helped me.
I take my pill when I wake up in the morning. I have extreme fatigue and migraines with my MS normally so I can't tell that is has made them any worse. I have been on Zoloft in the past and tolerated it well also.
The generic Lexapro is so cheap and that's a big thing for me being on Medicare D.
Maybe if you give it a few more weeks, it will kick in and you will feel better. I hope so.
