Sorry your are having to go thru all this .
Altho I have never taken Zyprexa (yet) I do know some people who are taking it and they are happy with there results .
I dont think there are any psych meds that dont cause the dreaded weight gain ...
Some Pdocs brush off complaints of weight gain .. I assume that they are just trying to get you stable and dont really consider the issues that are going that rear up if you pile on weight . weight gain is not a healthy option as it can lead to other issues ,, heart diease , diabetes .. causing self esteem issues etc .
Good Luck , hope you get good results
