I don't remember, or run out more often than not.
I pick up the boxes of Spec.K cheap (Price Rite) so it isn't too bad.
I know it's the right thing... but I can never get past the 21-day thing.
And when I do remember, it's usually around 10 AM already, and I'm realizing that I'm hungry.
Oh well...
As long as I keep trying..............
