I just got a fill on my band, hoping it would help me loose weight, although I am still going to convert to the sleeve.

Sometimes now with the band I get an air bubble stuck and cant burp it up. Does this feeling happen with the sleeve?

I had a band (SAGB) for 10yrs and I was sleeved in September. I can say there's no air bubble feeling - perhaps this is because there is no pouch.

I fully admit I have felt over-full and on two occasions I have yakked when I've chanced that one more bite, but unlike with my band, there was no foaming or sliming.

I do sometimes get "stuck air bubbles." It is just slightly uncomfortable and resolves within 30 seconds. Not a big deal.
