You should test it with a regular soft drink, like a Coke or Pepsi, as a control....................
I have.
Mexican coke raised it about 25-30 points in 20 minutes. Tried that a few times.
Don’t drink anything with hi fructose corn syrup.
Keep my type 2 under control, but it is not easy. But in my case it is *LITERAL* that “that which does not kill you makes you stronger”:-)
Gotta die of something, but I want it to be in a stolen helicopter for my 100th or shot by a 20 year old jealous boyfriend in my 90’s.
I wouldn’t worry about the sugar in energy drinks as much as the caffeine, guarana, and other stimulants. Arrhythmia is a real possibility.
