One envelope (6 per pack for a total of 36 in the whole box) makes 16 oz. of lightly-sweetened Starbucks iced coffee, so this will really get you going! If you normally use half-and-half or cream in your coffee, try mixing the powder from each envelope with 16 oz. of cold milk (full fat, skim, whatever you like) instead of water to get a richer drink than with cream alone (and with more calcium, too!). If you use skim, you actually get the effect of a large dose of creamer without any fat at all! And it tastes spectacular. I used to add chocolate syrup sometimes for a mocha, but I find it's so rich by itself that I can barely tell whether the chocolate has been added or not, so now I don't even bother. It's that good. I drink this everyday, year-round, and find it extremely easy to order in from Amazon to be sure of never running out. A total win for me. (But I don't think I'd have one mid-to-late afternoon unless I were planning on an all-nighter!) :)
