    I am 6mos out of Gastric bypass surgery, I find that I cant eat enough to give me the nutrients I need. I eat even a bite or two of anything solid and Im full, If I try to eat more I get sick and purge, I have to drink a protein drink every day to get the protein I need because I cant eat it. Is this normal?
    I do take multivits, folic acid, iron, and calcium, should I take anything else?
