I have the same type of stash in my car, just in case. Have not ever missed a morning dose yet, but it's there in case I need it.I have a small waterproof pill container I keep in my car glovebox with a dozen extra doses of warfarin and some low dose aspirin. Thats my just incase stash. If I should realize I forgot a dose, or in the event I don't get home until the next day I have pills handy. Its been relied upon more than a few times.
