Is it possible it wasn't a hangover? Most of my hangovers were in my 20, 30s and 40s, not so much in my 50s and hardly ever since then, so I might have forgotten. So remind me; how do you distinguish between the discomfort of a hangover and other kinds of headache, other than the fact that you drank a lot? I recall that one sign was that there was extra pain when I moved or shook my head, even with the mild ones.
