I have found that the chocolate drink is chocolatier than the chocolate pudding. I also love my chocolate drink really, really cold, and have learned if I shake it up and leave it in the fridge for an hour it actually thickens up. I eat the top part with a spoon and when it's all off I add two ice cubes and drink the rest. I also sometimes thin the remaining portion out by adding some more water. (Oh, and to start I use a pint size beer glass and fill it to the top with the recommended water amount, plus a little more when I "clean" out what's left in the shaker.) YUM!
Just thought I would share this 'cause I never left it in for so long to realize it actually thickens a bit!
