DenverSis, Welcome. I had a peg (feeding tube) and strongly recommend them as your sister needs her strength to fight this disease. When I was using my peg, I added Carnation Instant Breakfast to the drink and sent it down the tube as I couldn't stand the taste or consistancy and couldn't swallow anyhow. If you do a search on this site there have been a lot of discussions regarding diet and recipes for lots of drinks and slushes and milk shakes and such. With a tube you don't have to worry about it so much as you take in the calories through the peg. Hope this helps.
