I put the whole pack in. It was the lemonade flavor. I was full for the rest of the night. I have a magic bullet I filled one of the large cups up with ice and poured the pack in.
I'm going to sound like a total snot & I don't mean it this way at all...I drink TONS of those CL packs & the whole pack is actually 10 calories. Obviously still great, but only 1/2 is 5 calories which I think is stupid. Who's going to just use half!?
AGAIN, NOT trying to be a snot, I just thought they were 5 calories a while before I read the label right.
