Alcie has given you excellent advice. If you can manage to burp, Gas-X can help, but it won't do a bit of good if you can't. (I actually could burp a little, so it helped me--although there were times when my gas got ahead of my wrap so it couldn't escape, and bloating followed).
BEANO helped a lot, and I took the chewable tablets. I would chew 3 as I was eating something that tended to be a bit more gassy. Others have found a variety enzymes helpful, but I just used BEANO.
I agree with Alcie. At this stage of the game, try to avoid gassy foods. Also, no straws or carbonated beverages. Another trick...don't talk while you eat. All these introduce additional air into your stomach.
As Alcie said, it gets better over time.
