This was a good place to start. At first I tried the mocha, without any sweetener. I found it to have a long lasting bitter aftertaste. But I did like the buzz it gave me... slightly different than caffeine. Felt subtle, but long lasting. I came back to it and tried adding sugar and it was much better. Now I add sugar and a few drops of half and half, and I especially like the double chocolate. I ordered some more flavors. It's a bit expensive per cup, I would welcome an option to buy larger quantities at a discount. But for now I'm intrigued, and working it into my routine.
