What pill is a round yellow tablet imprinted with acp?

Answer 1

The docs in the Air Force in the fifties administered a pill called "ACP" ....sorta' like a panacea for every illness known to man. Believe it was acetaminophen, either codein or caffeine and, perhaps, phenobarbital.....not sure, actually, but they seemed to work.

When coupled with "GI gin", either clear or red, all your illnesses magically vanished.
