Gaseous First Fill....

I had my first fill yesterday since my surgery on 4-14-08, I started at 261 and now weigh 222. I lost that much without a fill, almost 8 weeks post op. Okay, the fill did not hurt one bit, better than I expected; however, I am burping up gas on my liquid diet, uncomfortable gas feeling in upper stomach. I will be on liquids 2 days and soft foods 1-2 days as well. Anyone else experience the gas after a fill? When does this sensation or uncomfortable feeling go away? I am keeping liquids down and plan on following the new diet to a Tee. I am thinking of drinking some hot liquids to se if it will help. Thanks for any comments.
