ABB Blue Thunder, or Extreme XXL, All flavors taste the same, Extreme XXL is just a really thick version of blue thunder. Make sure you take with Digestive Enzymes, else you will find out the hard way why they call it blue thunder.
As for my daily intake of fluids, I drink the generic Kroger version of Crystal Light. Fruit Punch tastes Awesome! And its generic so its cheap. cost runs about $1 per gallon. Highly recommend!
