Learning As I Go

I have always been an organic, whole-grain, whole foods type of girl. I, other than home-made Italian bread, cannot remember the last slice of white bread that I ate prior to surgery. My 13 year old son has known since he was a toddler to grab "brown bread" mommy at the grocery store. However after surgery I cannot tolerate wheat bread! Even the smallest, most well-chewed piece gets stuck! However I can eat white bread with absolutely no problem. Wheat gets stuck if its toasted, not toasted, no matter what brand, thickness, etc. I don't eat a lot of bread as it is, but I just find this so strange! Anyone else notice weird changes like this after surgery?
