It is mostly for sleep but I don't feel I sleep well with it and I've told my psychiatrist aboit my diabetes when he prescribed it. In higher doses the hunger isn't an issue bit that wss given short term after a traumatic experience. My sugars are always higher in the morning regardless of what I've eaten the day before. I'm losing weight fast too. I've had zopiclone before for sleep but it doesn't work like the seroquel. I don't have as many dreams or sleepwalking like I had with other sleep meds. This drug drains me physically though.
