In addition to the helpful (and much appreciated) suggestions you provided about various forms of bananas and leg-cramp prevention, I got some input on the topic from my close personal friends at whatever department inside Google decides which paid ads get posted on my blog.
And by the way, couldn't that department hire a graphic designer so these content-generated ads don't look so sketchy? Just from the look of 'em, every ad makes me think I'm clicking through to a scam.
At the moment I'm writing this, there's a mini-banner over there to the right about a product called Hyland's Leg Cramps. (I'm not posting a link because if you're interested, you should click on the ad. From click-throughs so far, I think I've made about eight cents, so by this time next year, I'll have earned back the 99 cents I spent buying Eben that song on iTunes.)
Anyway, if I were the good folks at Hyland's, I'd probably tweak the product name just slightly so it implied that the ointment or salve, or whatever the heck it is, relieves leg cramps, rather than causing them. Seems like someone in marketing or legal could have thought of that. It has quinine in it, so maybe I'll give it a shot.
