You've got pretty good progress so far Yamaha!! Congrats man. I know the feeling of loss of appetite with adderall. It's difficult to get over it and eat as much as you need to. I wouldn't quit the cycle now as you're in it deep already and shutdown. Even if you gain little mass and weight your strength should still go up somewhat which you can take advantage of later. If possible try vyvance or maybe take a smaller dosage of adderall to try and get some of your appetite back. Another option would be to "dirty" up your diet and/or start eating more calorie sense foods such as PB, olive oil, fast food, etc. not saying to go crazy on the fast food but a simple burger from most chains will get you around 25g of protein and around 4-500 extra calories. Another option would be to take in liquid calories. Make a few high calorie shakes with protein, milk, oats, PB, etc since liquid calories usually aren't as satieiting as whole foods. Good luck brother!
