I found out that Ensure is lactose free, i don't get any of theses symptoms I'm going to try an introduce that into my diet and see how I tolerate it. Also I found a milk product that is lactose free" Fair Life" products are lactose free. They come in no fat 1% which seems to fit in the diet as well. AL thought I do take a multi vitamin, I still need to find natural way to get vitamins like calcium. The GP diet is so low in nutrition and getting older I an concerned about bone health and getting enough vitamin "D". Thank you for all the input, I will post back how it goes with trying these dairy products.
