Single packets, have you found that you can't use the whole packet I can't with any flavor they are toooooooooooooo sweet. I love the lemonade ones but can only use 1/2 the packet in a 16oz bottle.

the lemonade is my absolute favorite. i use about half of one in 32 oz of water. lucky for me, we have a huge supply at work. i drink probably three things of water a day at work. trying to get more in!

Amy, you were banded on my birthday. :-) Congrats.

I'm still able to drink whole ones, but I never put them in 16 oz bottles, 20 or higher. A lot of the time, I will refill the bottle with water when it gets about half full, then I enjoy it best. I haven't found a way to hang onto an open packet and I still can't waste anything.
