I have gained approx 3 stone from zyprexa. I lost 3 stone last year, all the 3 stone has been put back on. I was warned by the doctor that i will crave food on zyprexa but i said i did not care but hmm im starting to. I got weighed today i am 18.4lbs compared to 15 stone not that long ago. I'm going to quit the zyprexa. I have been eating very healthily now and walked for about 30 mins. I will be going to diet class every friday again....let's see how this goes.
