Health Food Stores

My son has a little digestion problem. Little isn't really what the problem is...but he requires the use of enzymes to help his body digest all of the foods he takes in. When these enzymes are lacking he will literally clog the toilet every time he uses it! I have been out of his pills for a week or so, and had forgotten all about them, until I walked upstairs to see that not one, but two of the toilets are clogged! So today, with my GNC coupons in hand, I'm heading off to the health food store to purchase his enzymes. I'm hoping this is a problem he grows out of, but I'm thinking it may be something he'll be dealing with for the rest of his life. Poor thing!
