My experience is only deal with a G tube although it's applicable to PEGs (a type of G tube inserted with an endoscope instead of using a flouroscope) except for insertion/replacement.
I had to work up to using a syringe bolus feeding. I started with the gravity feed bags. I also supplement my Jevity 1.5 with real food, the exact same dinner that my wife cooks for us, put into a Vitamix and syringed down my G tube.
I've failed four MBS tests - guess I need to study harder.

I wish you much better luck than I had with Vital Stim.
I also wish that this is just a temporary condition for you. The longer you have the PEG or G tube, the more you hate it.
