I have worried about you being a foodie and having to deal with pancreatitis concerns. Sorry to hear your appetite is not what it once was. Give yourself time. You are still recuperating from a major illness. Same with your hair. You have been severely nutrition deprived. The hair loss is likely a reaction.
Oatmeal: I don't even want to tell you what dad puts on his. He eats the brown sugar version and adds butter.
Even with his excessive butter consumption, his cholesterol improved tremendously. Need to get him to exercise more though.
