My doctor put me on Victoza about a month ago. I have PCOS, Insulin resistance and also am pre-diabetic. No matter what I did, weight never came off. Victoza along with the Metformin, has been working. I lost 20 pounds in the first three weeks, and my apetite has nearly gone away.
My doctor suggested that I take Victoza at night, right before I go to bed, so I will be asleep during any side effects.
I am lucky in that it has not bothered me that much. Sometimes some gas in both directions, but otherwise ok.
Try taking your Victoza at night, that might help you. And in some patients, I have read the doctor had to reduce their dose and they did better after that.
I wish you luck, keep me posted how you made out.
Also, I have read that for some people the side effects went away or greatly reduced after they were on it a while, you know - like 2-4 weeks. Give it a little time. Wishing you the best. For me, the medication is helping me.
