im at 22 days since my banding and doing great, i also had terrible gas for the first 2 weeks, on my 3rd day home i thought i felt like i had a knife in my throat everytime I ate or drank, i sat on the edge of the bed and put my hands against my stomach and rocked forward a few times pushing against my stomach and BAM!!! I burped for 20 minutes straight, and i'm talking 10-20 seconds at a crack, now when i feel the gas building i just do the same thing and it pushes it right out!!
