Blue Diamond Almond Breeze Unsweetened Chocolate milk can bee a nice alternative for you though. If you are going in expecting it to match regular chocolate milk you will be disappointed. It isn't that sweet and that give the impression that it is watery. At first I was like all "ew, who wants water chocolate milk." Then it hit me. I quick did a spoonful of Splenda (or other sweetener) mixed it in and in no time I had a delicious treat.
That being said, if you don't care for almonds it does have that taste, but if you love chocolate and are missing those treats this may be a good substitute.
