I saw this at a local CVS store a couple times right next to their own, knockoff, brand. The knockoff was about a quarter of the cost, so thought I'd try it AND LOVED IT.a couple months later, their price had gone up and Amazon had it at a decent rate, I figured I'd give it a go.UGH!Maybe it matters that I dilute the knockoff in 40 oz of water (2 20 oz bottles that I take to work)This stuff is only tolerable if mixed in less than 12 oz.I think I found someone to take it from me. I'm going back to the CVS brand.
