@ddude1116 I disagree. Orange juice has the same amount of sugar as Coke. You are only going to get a headache withdrawing off of Orange juice if you deprive yourself of the minimal carbohydrates you need overall, and that still is not directly related to the OJ. If you switch from regular Coke to Caffeine free Coke, you will get the headaches and overall yuck feeling, and sleepiness.
Coffee drinkers who take it black are not relating to the sugar, they will get caffeine withdrawal. It’s true coffee has at least double the caffeine as Coke, sometimes higher, but coffee is usually consumed in 8 to 12 ounce increment, while soda more likely 12 to 20.
