Hungry. I know it is the Seroquel doing it. For the last two days I have been on the Optifast diet which consists of milkshakes, health bars (like muesli bars) and one meal a day which is a normal dinner. I have eaten that (which was a baked potato) and I am still hungry. I have been thinking about it and it looks like I have gotten used to eating so much more which has been my downfall.
