Are there appetite suppressants? I take seroquel (quetiapine) its the only stronger medicine that helps me sleep but I gain weight I lost 54 pounds on suppressant

Appetite suppression. Yes, there are appetite suppressants that can be prescribed -- but can also aggravate other symptoms. I believe you wrote about having been on adipex previously. Other possible helps could be topomax and metformin -- not really "appetite suppressants" but may help with weight gain. Best of all is for you to increase activity and review your foods carefully with a nutritionist. Be well.
Yes. But you will need to talk to your physician and get a prescription for this medication. It is serious business.
