"my rheumatologist put me on lexapro for both depression &amp; fibromyalgia, after cymbalta stopped working for me. i started it two weeks ago tuesday &amp; i absolutely love what it&#039;s doing for my depression &amp; anxiety but hate that it&#039;s caused me to gain at least 5 lbs already. i&#039;m going to try to stick with it for another 4-6 wks, but if my weight continues to increase, i&#039;ll have to wean off of it. i dread weaning off of antidepressants."
