Neither do I. My old commute was about 15 miles and I had a few long lights at the start so those dark and chilly mornings were made nicer by a wonderful brew.
I lost another mug a few months ago due to a weird bump and bounce over a man hole where my mug flew out and tumbled down the road at rush hour. Since then I have stuck to the dual thermos in the pannier. It used to be thermos and mug, so the second thermos was no big deal.
