I did a Google search for night sweats (sleep hyperhidrosis) and found that, amongst other things, it can be related to head injuries and epilepsy. There was this link and there also was this one. Since I seem to have this condition, at least to a degree, and I take an anti-convulsant for what we think is likely epilepsy (I've had a few seizures), these were particularly interesting for me. I had never made this association before.
And I'm making this entry in the Burble primarily so I don't lose these links.
