It looks like you did a good job with your diet today! It's hard to change, isn't it? WHen I was first eliminating foods and trying to figure out what triggered an attack in me, all I would dream about was eating steak, pizza, milkshakes. But eventually you find food you really like, that tastes as good--if not better--than the triggers. Plus, you'll start feeling better physically. If you want to see what someone with IBS typically eats, you should check out the IBS Fitness board--many of us post our daily meals there.
Have you had soy milk before? It can take a couple of weeks for your body to get used to, so you may experience a little bloating from this. The grilled chicken breast was an excellent choice and the turkey wrap sounds safe. Wraps are safe as long as they don't contain the triggers--avoid creamy sauces, cheese, etc. I don't know about the pickles--although I haven't had problems with pickles. Did you have raw carrots or cooked? I learned the hard way that for someone with IBS-D, raw carrots can be difficult to digest, which would cause more bloating. Steaming carrots is easy.
Have you tried taking Phazyme or drinking fennel tea to ease the bloating?
