Here is better advice...consult your doctor who prescribed it...tell him your concerns and ask him if you supplement something like Anabeta to increase your appetite.
If you like the idea of smoking weed and medical marijuanna isn't legal in your State YET (because eventually it will be legal for everyone but government employees and professional athletes) Ask your doctor about Dronabinol. It is prescribed to restore your appetite. This is a medical form of marijuana that contains cannabinoids such as THC, which help increase appetite...
I doubt you could ever get this prescribed to you as a young adult. It is probably used for recovering Chemotherapy patients and other diseases and treatments that cause muscle loss, appetite loss, etc...But hey, I told my doctor "I can't concentrate, I want Adderall" When I was in highschool and he prescribed me the Orange Time Release good **** pills...Maybe saying "I'm not hungry" will get you some synthetic weed.

EDIT: Also...B-Complex Vitamins, Supplementing Garlic and eating things with Chayenne Pepper are also godo ways to boost your appettite. Choke down a weight gainer if you can't get your normal calories in.
