I just buy the 5 lb jugs right now. I have ordered by the pound before though.
I'm with you... the fruity stuff makes me sick. Not really, but I don't like it. I lived on chocolate for a long, long time and never noticed the vanilla milk shake flavor. I ordered it for shits and giggles and have been in love for about a month. I might just be the newness and change of pace relative to the chocolate, but it's good stuff.
My during/post workout shake I currently mix with water and some carbs.
When I'm bulking, I generally always mix with milk, just b/c I like the calories and it tastes so much better.
When cutting, I generally use water.
My morning shake that I have just about every day at the moment is simply:
1/2 cup milk
1/2 cup yogurt
1 tblspn natty pb
1 scoop whey
1 frozen banana
2 ice cubes
Blend to a smooth texture and presto... perfect way to start off your day!
