Used to drink a lot of the Costco version; sold by the box(48 bottles). Didn't like to drink coffee;
and this was simpler to keep and consume. No lines, cleaning coffee maker, sugar, cream, etc.
After a while of daily intake; seems to have lost it's effectiveness. Then Costco came out with a
"Extra Stregnth" version.
I drink it once in awhile now; started having coffee everyday.
