I don't have problems with chewing or swallowing, but I do have a problem with "smacking" my food when I chew, a habit I developed from my years of living with buck teeth. Even though braces corrected the problem back when I was 12, I'm still noisy when I eat to this day.
I'm also a ridiculously messy eater. During every meal, without fail, there will be bits of food all over the area where I sat, and stains all over my clothes. I'm not quite sure how this happens, but it does and it's embarrassing.
