"i am about two weeks into taking escitalopram.  the first two days were side effect free. but after that i was vomiting constantly and could barely eat anything. i have lost five pounds and i am already a small girl. i experience very mild headaches here and there. mostly at night when i am trying to sleep. one minute i am constipated and the next i have diarrhea. not cool. i cannot eat much at all, have not lost any sexual interest. now that i am two weeks into the medication i am experiencing additional anxiety like heart palpitations and feelings of wanting to break down crying over nothing.  i used to be on a higher dose of &lsquo;citalopram&rsquo; which caused no side effects but this one is hard on my body. hope it works for my anxiety eventually"
