LOL on your picture!
When I have to have a fasting blood test — even with ‘’no black-no sugar’’-coffee, I always take a thermos of some with me. I tell the tech who is taking the blood to leave the needle in so I can pour some coffee in!!
I went from regular caffeine coffee slowly ——to mostly de caf, (because of heart beat problems), but even with my mostly decaf, I HAVE to have it first thing in the morning!!
