| I take it you do not keep glucose tabs in your pocket or glove box? I would go get some, ASAP.
Chocolate has fat and does not absorb quickly enough.
Drive safely -- lucky you were not hurt, or pulled over as drunk.
I just read an article on the merits of carrying glucose tabs by David Mendosa. They are cheap, readily available, easy to carry, and do not go stale. Hopefully this won't happen to you again, but be ready!
