I used 2 drink xp maximum, i mixed the powder with water, it became a chore every morning having 2 make it over and over again. but now I have 2 have 4 a day instead of 3 a day so i have to take the cooler packs 2 skool . At least they look good. When i drank the powder maximum i used 2 have it with a straw because it tasted horrible without it. It was kinda embarrasing @ camp.
