I am sitting here looking at a bottle of Zyprexa 10 MG. After reading all these comments I am scared to take it. I do not want to gain ANY weight my only problem is racing thoughts at night and not being able to turn my mind off and go to sleep. Once asleep I am ok... My doctor has tried many things to help me go to sleep and none have helped. Do I dare try this drug... I am reading about 20 to 30 pounds weight gain in a month. That alone would depress me. I am 5'5" and weigh around 135. Does everyone that takes this drug gain weight?
