I recently had a major surgery. Once home from the hospital I went to open my favorite drink, Diet Coke.....I took 1 drink and thought YUCK. I drank Diet Coke for more than 12 years and now I cannot stand the taste of it. Is there any relation between surgery and taste buds or tastes? Since my surgery a little more than 3 weeks ago, I have not had a single one or crave them like I used to. Oddly enough, my mom did the same thing when she had a hysterecomy (I too just had one and a little more done) Since my surgery all I can stand to drink is water and a few other things, but not my old fav, Diet Coke.
