I've been vomiting for like 8 months but i want to stop, it is a voluntary vomiting, not so often, like 1 or 2 times a week, just if i eat too much, but either way I want to stop it, I want to know also if getting a blotchy face after vomiting is normal and if I stop doing it, will my face and metabolism return to normal? or do I need some kind of treatment.. can I fix everything i messed up those months?..please I need help, thanks..
