Keep the PEG, your mouth will likely get worse, and you will really need it. As with all things, there are techniques that make it easier to use. I too got nauseated every time I used mine in the beginning. I found that I couldn't put anything really cold in it, and that I really had to S_L_O_W down the drip rate. As an example it took 90 minutes for me to have 4 cans of Ensure and two of water drip into my stomach to prevent me getting queasy. Of course since I was sleeping and tired all the time this just meant dozing in an easy chair in front of a TV while the process took place. That reminds me of something else don't do this lying down, another cause for problems and stay sitting up for at least 30 min after you have finished. Make sure they have really trained you on infection prevention and cleaning of the tube itself inside and out. Nothing is more of a problem than a clogged PEG. If they haven't, just say so and you'll have a bunch pf people besides me here giving you the fast track to success with the PEG
