I'm sorry but if you are suggesting this as advise, its not good advise for his particular case because everyone with CF is different and you haven't even gotten all the variables yet.
What forumla? What rate are you going at? What is your tolerance for max VTBI per night? How many enzymes do you take with a normal meal?
I am extremely PI and I take around 25 ezymes with my 2000 calorie feed. I take 10 at the start I wake up 4 1/2 hours into it and thake 10 more, and at the end I take 5. I take MT20s. While it is ideal to get enzymes throughout the feed they wont suggest it because they think most people won't wake up. I get much better absorption when doing it this way.
Your dietician will be able to figure it out based on the amount of fat in the feed, because enzymes are dosed off of lipase. So take the total number of enzymes you should need, and then divide it by how many 5 hours you want to run it for. So if you run your feeds for 10 hours and you are supposed to take 20 enzymes for the amount of enzymes you should take, you'd take 10 at the start and 10 in the middle (5 hour mark). General rule is enzymes in the gut last 4-5 hours.
I run at a rate of 130ml/hr to 170ml/hr depending what I'm trying to accomplish.
I will say that YES it is difficult to fall asleep when feeding, so try melatonin as suggested above, if that doesn't work you may want to try something else.
