Don’t last
Size: 1.86 Pound (Pack of 1)
I really wanted this to work. It was great the first 4 days or so but now no longer helps.

Don't expect it taste like the original
This does not taste like the original with sugar, and if you drink this right after drinking the other one, you can taste the difference. But it's a heck of a lot better than the off brands with stevia. If you give it sometime and forget what the original taste like, this is great! I like the fact that it does not have sugar or aspartame. It works good for regularity. I used this twice a day after surgery with lots of water to help with the anesthesia constipation and have continued to use it.

Great product for intestinal health
I've been using this product for about 6 months and it has helped tremendously in reducing diverticulitis flare ups. It tastes great and is easy to mix up with water. Best to drink immediately.

Taste is tolerable. but it does its job!!
I am not crazy about the flavor, but I can't tolerate sugar. It is better than plain. Just add a little more water and drink it down fast. It does its job. I have diverticulosis, so I need to keep my fiber up. Helps with controlling appetite too.
