I had another thought -- a lot of places will put dairy in their turkey lunchmeat. I read the package in my store. You may need to stick to chicken breast instead for your sandwich. Maybe that will help. Dairy is a big trigger for gas & bloating. You also could try using a digestive enzyme to help. It doesn't mean that you can eat the things that are bad like dairy and fatty foods -- but it does mean that what you do eat will be better digested by your body. The one I take also has a gas fighting ingedient in it. It's called Digest Support. I actually take two pills twice a day --- I take it with lunch and supper -- but they suggest taking two pills a day and you could take one pill with lunch and one with supper... or one with each meal. Just don't try and break the rules because you are taking them. It won't make it okay to eat dairy products for example. Here's a link that talks about them. I order mine off the internet because I live in a small town - but you may be able to find it.
