Nice to see you around, mr big cheese, sir...
Headaches gone, and I'm a bit more awake now. Avoid high fructose corn syrup if you can (sucks they even use it in gatorade) Yeah I used to drink about 4 cokes, 2 with supper and another 2 with another big meal later. (I'm a night owl, supper is breakfast for me, and then I make something around midnight or so)
Diet can be worse because of the aspartame. The very best drink I recommend is Propel Fitness Water, berry or grape. Decent taste, zero calories, zero carbs, no HFCS, lots of vitamins. Not a fizzy drink, but very mild compared to fruit drinks. It's everything Gatorade should've been.
I'm normally not bothered with any issues involving caffeine, but when you go from a bunch of cokes everyday to a week or two cold turkey, the first couple of days tend to suck. Not a good idea to mess around with ones sugar intake either, as this could result in problems... like ugh diebetes.
