I've been getting cramps in my feet recently. I suspect an herbal tea I've been using. This isn't the first time I've had that effect from herbal tea. That's the trouble with anything herbal. Many herbs are medicinally active in one way or another, and just about anyone is likely to be sensitive to at least some of them. I'm not sure which ingredient in the particular tea blend I've been using is likely to be at fault, but I quit using the stuff a couple of days ago and the cramps are gone. Back to the orange pekoe, I guess.
The temperature is going to be getting down into the fifties at night for a while. Happy.
