I am on zyprexa and it is notorious for causing wait gain. What I have done over the last few months is eat a low carb diet which I should be eating anyway being that I am diabetic. I have also started walking a few miles each evening good for my metabolism plus it gets the dogs out. I also weigh myself every morning and every night. I fluctuate between 174-180lbs but I really stay on top of it. This is what works for me. Good luck!
