Let's get this good ol', totally a waste of time (maybe) chocolate milk. All you need is: raw unsweetened cocao powder, raw powder stevia, vanilla extract, peanutbutter, and milk. By the way, the peanutbutter is optional as it is just used as a thickener. It barely alters the taste so quit your commenting on this beautiful peanutbutter.

1 tbsp of cocao powder
1 tbsp of stevia (alternative would be 1 tbsp of raw cane sugar or just sugar(probably the better option because stevia is supposedly bad GG))
1/4 tsp of vanilla extract
1/2 tbsp of peanutbutter
1 1/2 cups of milk

All you have to do is mix all of these ingredients in a blender, or shake it really good, and viola! You have some almost sugar-free, healthier, chocolate milk. This will make you feel good as you game and fuel your game! *DISCLAIMER* This is not 100% guarunteed to work, but it definitely is pretty good if you have the right taste for it!
