I thought about checking the Jevity ,because you are right, the TSA doesn't care about it in your luggage. When I weighed the jevity cans I would need for a week, they came to 35 pounds which would have meant either wearing the same clothes for a week (worked for me, but my wife nixed the idea) or else checking a second suitcase. It was cheaper to buy Ensure the whole week rather than pay $25 each way for $50 and much much easier.
As for "hunger", I don't really feel it either. But now that I am using the syringe and not even one gravity bag, I do get a "full" feeling. It's a blessing not to be "hungry" as apparently some G tube people still feel all those hunger pangs. My guess is that neither of us need any more problems or disappointments in our lives, so I'm glad not to be "hungry".
