I'm not sure if you read my post, but I lost the weight I gained and got back to a BMI of 22 just by going off of the med I was on. The med caused cravings and lack of satiety. Going off the med reversed the cravings. This demonstrates that cravings are biological and not caused by a lack of self-control, because I didn't need self-control before or after, and I didn't have the self-control to avoid gaining weight while taking the medicine.

Craving sweets is a well-documented side effect of mirtazapine, I'm not sure why you're having trouble accepting that.
