did you eat sugar?
I had that happen to me. When my body was so clean of sugar, then ate even just a bite, I woke up in extreme pain (in kidney). Must say it helped me stop eating sugar in the beginning of taking it out. Sugar = Pain. (granted I tested it a few times before I finally got the message) I also had it happen to me after using Truvia at Thanksgiving. The erythitrol (spelling?) caused the same reaction. I didn’t understand at first since I knew I didn’t eat sugar, but by process of elimation I figured it out. Knew it wasn’t the stevia.
Couple months ago I had a bite with sugar in it, and hour or two later I had chest pains from it. Was wondering if having hypoglycemic reaction since blood sugar was so low due to diet.
Finally I had real chocolate for first time in 6 months the other day, and had no problem. About a month ago, I added back oranges and a banana every week or two. I think perhaps having that tiny bit of sugar in my system has helped my body accept it better.
