Ex Input:
I have been searching for a natural lemonade drink mix that would actually taste good. This is not one of them. Did not like the the bitter taste of this drink mix. I can make my own fresh squeezed lemonade better than this stuff. In the mean time I purchase Newmans Own ready made lemonade if I don't have the time to make my own lemonade.

I bought this at a local gas station near my house and was excited to try it because I see it everywhere. It was nasty. I will never drink this crap again, I don't care how "good" it is for you. The taste is disgusting and I'd rather just drink regular water. Blah!
