"Tasting like sweat" is definitely going to be a personal decision. I usually mix mine with somewhere between 16 and 20oz of water. I didn't like fruit punch either. Our go-to flavors here are:
-Lemon Lime
-Strawberry (my kids like it, it's not my favorite)
-the current "firecracker" one that looks like a popsicle on the bag (this is the favorite right now)
-pineapple yuzu (caffeinated, 2nd favorite)
-seaberry (not my favorite...pretty mild flavor)
-orange tangerine (vitamin c, in the winter)
in sugar-free the white peach is decent.
I'm also going to throw out there that even with the
amazon sale, you can get these WAY cheaper from costco, albeit with more limited flavor options when it goes on sale for $21.99 for 30 sticks (26 sticks in sugar-free flavors.) If you have a bunch of people in your house who are active and drink these regularly, you can basically pay for a membership just on stocking up on these. AND the online price is the same as the in-store price and includes shipping/handling. You'd break even on the cost of a membership when you bought your 8th pack. The caveat there being that they only go on sale about 4 or so times a year I think, and sometimes it's not all the flavors.
