Let's see... early on, it was scrambled eggs. That one is really common. You think it will be mild on your tummy, but you'd be better off with a fried or hard boiled egg because scrambling makes it really textured by comparison and for some reason, it's not good. I also struggled with broccoli and asparagus unless it was steamed to the point it turned to mush. I had a problem with reheated foods, too, so cooking up a big piece of salmon or chicken and then portioning it out for a few meals was a no-go unless I ate it cold. I could reheat ground meat, though, especially if it had a sauce with it.
I would say that 99% of the time, none of these things were a problem after about 6 months. What I do still struggle with is if I forget to eat slowly and take very small bites that I chew thoroughly. In the beginning I used a cocktail fork to remind me to take tiny bites. I would chew for a minute before swallowing. If I didn't, I would get sick. But as time goes on, you can eat a bit more, chew a bit less, and get away with it. Until, like this morning, you are in a hurry and inhale your food without thinking like you did pre-surgery, and realize after about four rapid bites that this was a huge mistake. Sometimes when that happens, you will be in pain for a while and then it will subside on its own. Sometimes, it will come right back up. On the bright side, it is not like pre-surgery with that awful vomit taste and smell. It just looks (and tastes/smells) like chewed food, sometimes with some foamy mucus, and it's fairly quiet, too. (Sorry if that's really gross to describe, but I figured it's good to be prepared). One thing I did was order a pack of the motion sickness bags you can find online. I put a few in my car and tucked one in my purse. That way, if I was ever in public and ate something that didn't agree with me, it was much easier to be discreet about it.
With dumping, in my experience, every so often if I have something sugary, I will experience an increased heart rate. It's not a big deal and it slows after about 15 minutes. But on Thanksgiving, my cousin made a green bean casserole that was very fatty with a ton of butter and cheese. I had a single bite of it, and maybe 20 minutes later my heart was pounding like I had just gotten up and run a lap around the block. It went away after about 15 minutes as well, but definitely a stronger reaction. But that's it for dumping for me. I've had enough sugary and fatty foods that I'm fairly confident I am one of the 70% who only experience very minor to no symptoms, unfortunately. I wish I had something to make me not want to indulge!
