Hi Shelly, Up here in Canada a dietician comes in and figures out how many calories are needed for each person and then perscribes the appropriate nutritional supplement.
We have not had any problems taking of the tube site. Sis finds she is not pressured to eat anymore. She too was choking and taking a long time to eat. She also takes all her meds. by tube.
It has definitely been a plus for her.
Hope you get the answers you are looking for.
Good Luck,
Jane
