What can be done to cut appetite? I'm on 200mg seroquel (quetiapine). Trazodone didn't help I was tortured so I have trouble sleeping what can decrease hunger

Self control. Unfortunately seroquel (quetiapine) is known to increase appetite so stopping it would help but you must weigh the risks and benefits and discuss other options with your provider. Dont stop the medication on your own. Good luck.
Appetite Suppression. There is really no effective medication or pill or supplement to do what you are wishing for. But, if you decrease your sugars or carbs in the diet to under 25% of your calories you will experience less hunger and less of an appetite. This happens when the majority of calories are proteins and is one of the newly scientifically proven secrets to permanent weight loss.
