i swallow a drink that i buy from netrition.com
it has 215 grams of carbs, 50 grams protein, and 1/2 a gram of fat. It's 1090 calories, and has 8 grams of glutamine. I dig it. Tastes good too.
You have a choice of flavor and sweetener, may be, you missed that part?
Also, for the quality and price, you can make it taste better yourself.
Personally, I don't care that much about taste, I use it only after workout, no big deal.
