Each year I have to have a glucose tolerance test to test for diabetes. I went in this morning after fasting since mid night. They drew blood and shortly after I had to drink a very sugary drink. They usually use a drink called glucola, but in the past it always made me sick so they weren’t able to complete the testing. So, I use a substitute. Today I had to drink 20 oz of root beer. Usually this wouldn’t be a problem for me, but since it was first thing in the morning and on an empty stomach I got a tummy ache. They then drew blood every hour for the next 2 hours. They don’t have the results yet, but when they do, ill update!
