I have been taking 40 mg of lexapro for about 2 years. I recently tried to taper off of it over one month reducing by 5mg each month. The withdrawal was so bad the last week I went back on it out of desperation. Now I'm not having the same horrible withdrawal symptoms (constant weeping, stomach cramps, panic attacks) but feel terribly depressed even though I am back on the original dosage. Did tapering off and then going back do something metabolically to my system. Any suggestions. I feel like a huge black cloud is over me. I wanted to go off of it because I did not feel I needed it anymore and because of the cost. Also, once I started reading about it, it seems that 40 mg is more than most people take.
