I went to the mall with my son and couldn't resist the pretzel bites from the place there. They were so good and they were soft enough for me to chew. However, my mouth is so sore and I have sores on the inside of my mouth where there hadn't been any for quite awhile. I just don't get it, still don't see why I did this. I'm just not seeing the good in any of this other than being miserable.
