Coffee or not to coffee?

[harm_less]

Unless you have a nasty headache, in which case wash your medication of choice down with a strong coffee. It multiplies the effect without threatening the liver...

Yep! But if you're in North America most analgesics have caffeine included in their formulation. I struggled to source such products in Canada while there in 2004 without caffeine, which I was wanting for pain relief from an arthritic knee during the nighttime without sleep disruption from the caffeine.
