Sorry to hear you are going to need the tube. If it is a regular peg tube thru your stomach, then the following applies. (not sure what you meant by
tube thru my throat) You will be sore for a day or 2 after the surgery. You will want to ask for an automatic feeding pump. You can then do you feedings overnight so it isnt so much to do during the day. You will want to use the prescription formula the nutritionist or gastro doc prescribes. It is balanced nutrition with all the nutrients of food. Dont be upset if you go thru a few kinds before you find the right one. Now you dont have to taste yucky medicine anymore, put it thru the tube

Several pointers.....
prop yourself up to eat
add water to the formula
keep the feed rate slow to start
flush before and after feedings
flush before and after taking meds
use the drain sponges around the peg site, add a dab of antibiotic ointment
make sure you swallow at least water everyday
still try to eat food daily to keep the chewing and swallowing ability
Best of luck with your surgery.
