I bought about 5 weeks worth off Amazon and started today. I tried one last week as a meal replacement just to see what it tasted like (that was vanilla, today first meal was chocolate). I like the taste - I use one of the GNC-brand short shake cups with the wire ball to mix, and fill the cup to the 12oz mark with water/ice. That's just my preference, with that amount of water, to me the shakes take like milk (vanilla=sweetened milk, chocolate=chocolate milk). I know that cutting the tangible food, chewing, etc. out of my life is going to be HARD, but it is worth a shot!
Good luck to you - if I can be of any help please let me know.
