Wow Rose.. over 3 months out and that's all you can eat

I'm really sorry!
First.. get a pill splitter.. it is small and easily packed with you, so even if you get a delay at the airport, you can still take your meds.. I paid less than 3 bucks for mine at the drug store.. Next, I would check with the airlines about bringing medical equipment.. how much does your CPAP machine weigh? Is the 50 lb limit for the first bag with extra charges for anything more?
And if I were you, I'd look into a 'magic bullet' thing instead of a blender which I think is more compact.
As for the shrimp.. that seems to be a popular meal shortly after post-op.. maybe try some at home before you go to see if you tolerate it? Can you have chili? I never liked it before, but I tried it recently and really enjoyed it!
I hope you have a good time in LA.. I used to go to NO annually for vacations.. and had a great time.. I'd love to go again, though the food would be sooo tempting.
Have fun!
