I have been on lexapro for about 9 months 20 mg. I too have seen the weight gain 20 lbs, the mood changes. I get mad and im very inpatient. I dont like to be around a huge crowd of people. I want off this drug. I always heard u should never stop or try to ween urself off of it unless its done by your dr. I too feel the dr knows nothing but to give you more. I do notice at night i get this tingle feeling in my feet and sometimes in my hands. im wanting to start just taking 10mg a day for a week then the next week 5 mg and then maybe every other day of 5. what do u all think.
