Does it have the directions on the side of the container? Usually it gives you the suggested tablespoon dose and you mix it with water. Easy peasy. From what I remember, the longer you let it sit, the thicker it gets and the harder it gets to drink- thicker. 

I take It up to three x day. I follow the dosage on the package and I mix it in anything I am drinking, water, tea, coffee, juice. I have Not had an issue with Benefiber thickening. 

Thanks to both of you
