Hi,
My husband had alot of trouble with nausea when he used Ensure in the Peg or tried to drink it. He found that he could handle Boost better (Boost Plus has more calories). Everyone is different, but it might be worth experimenting with some different products. Another one that he tolerated well adn that had tons of calories was Novasource - you can't get that at the grocery or drug store, you have to order from a special catalogue (as far as I know). Good luck in your recovery.
