Gary, there are folks on here that have far more experience with pegs than we do. But John has had very little problem with his. To answer some of your questions: They should send you home with several syringes that fit into the top of the tube. John's came with a pusher that he never uses. He just pours the nutrition down-thinned or mixed with water, broth etc.Example: He pours a can of 2CAL into a tall measuring cup, puts 16 oz. of warm water into a second measuring cup and alternates the two until the 2Cal is gone. Cold water or juice is uncomfortable for him. How much you can put down the tube at one sitting is really up to you. I think you will be able to tell when you are full. You don't want to make yourself uncomfortable. You DO want to get the right amount of calories and water a day so you will just have to experiment. John lost alot of weight between March and mid July [he was really sick] now that he is feeling better, he is taking 4 cans 2Cal daily [1900 cal.] plus Welches Concord grape juice [8oz =170 cal] plus Clamato juice mixed with a regular beer [240 cals]Gatoraid is good if you start getting dehydrated. We do try soups too, but most of the canned ones do not have alot of cals. You can fortify soups with powdered milk mixed into whole milk or cream. Egg Beaters are great to add to soups, etc. Never eat raw eggs! I went to Yahoo Search and typed in "high calorie liquid diet" and got some good info there. We also use Pepsid on occasion and Benefiber [all of his meds. go thru the tube.
As to using 7-up , etc. to flush the tube, I don't see why not-- it's more hydration. You'll do fine. Amy
