Have you tried cannabis of any type? It's the best, and only, medicine for increasing appetite that I know of. That's why everyone knows it "gives you the munchies." Most people see that as a silly thing to make jokes about, but for people with chronic illness and other reasons for upset tummy and lack of appetite, it's downright miraculous! It's still illegal where I live, but being able to eat a good meal outweighs that cruel and inhumane law, simply based on humanity and compassion. Considering benefits vs. risk, and a life at stake, obviously there's no debate. Idk what's available or how in the Philippines, but something to think about. :)
