Flying with a band

Wow, I know this is going to sound REALLY dumb....but has anyone had any problems eating during/after flying that has a band?  Can the pressure changes affect restriction?  Seriously....I flew to Baltimore Saturday and couldn't keep anything down Sat evening.  By Sunday morning I was almost okay, but after coming home Wed, I couldn't keep anything down again.   I feel almost okay today but everything seems so "tight".  Does flying cause this (I am certainly not stressed about flying, I love flying and I know stress will close me up like a rubber band)?  
Thanks for any help!

Richard "slimes and foams" while we are in-flight.  I will get stuck if I nibble or drink cold fluidswhile in-flight.  I usually stick to warm fluids during the flight.  My first meal after flying tends to be mushy and then if everything is OK I progress.  Richard, being a he-man simply eats right away and yaks if he has to!  Not smart but I'm not his mommy so i just stand by with an "I told you so."

We have flown once for vacation since being banded but this encompassed layovers so it was actually 4 take-offs and landings.

 if you ask this on the band board I think you will hear about it alot!!! I think the tighter u keep it the more it affects it!!
glad your home safe and sound!!

I flew recently with no problems but then I was on a considerable amount of dramamine and pain meds. :)
