Within the first 10 minutes
10 teaspoons of sugar hit your system. This is 100 percent of your recommended daily intake, and the only reason you don’t vomit as a result of the overwhelming sweetness is because phosphoric acid cuts the flavour.
Within 20 minutes
Your blood sugar spikes, which causes your pancreous in turn to emit an insulin burst. Just like a domino, your liver will in turn respond to this by changing any sugar it can get its hands on into fat. (And you’ve just ingested plenty of sugar, so your liver is finding alot to work with.)
Within 40 minutes
Caffeine absorption is complete; your pupils dilate, your blood pressure rises, and your livers dumps more sugar into your bloodstream.
Around 45 minutes
The dopamine production in your body is increased, which stimulates the pleasure centers of your brain. Heroin, and most other drugs, work in exactly the same way.
Over 60 minutes:
The phosphoric acid binds calcium, magnesium and zinc in your lower intestine, providing a further boost in metabolism. This is compounded by high doses of sugar and artificial sweeteners also increasing the urinary excretion of calcium.
The caffeine’s diuretic properties come into play. (It makes you have to pee.) It is now assured that you’ll evacuate the bonded calcium, magnesium and zinc that was headed to your bones as well as sodium, electrolyte and water.
As the party inside of you dies down you’ll start to have a sugar crash. You may become irritable and/or sluggish. You’ve also now, literally, pee’d away all the water that was in the Coke. But not before infusing it with valuable nutrients your body could have used for things like even having the ability to hydrate your system or build strong bones and teeth.
