My father used to get it, and I started getting it in my 40s. One time, after a drunken gambling binge in Dakar, I woke up in my hotel with a bad case. I actually saw an African doctor, who gave me something, although it helped only temporarily. I could hardly walk, and I was visiting these national monuments with a thousand stairs. My father used to drink cherry juice, and said it helped. I became a vegetarian, and although I certainly still drink, I gave up beer, and my last episode was years ago.
