What do you think of melatonin? I'm thinking of starting it not so much for the potential sleep benefit as its antioxidant power. My cell membranes are getting trashed while I sleep, I believe, because of the unmitigated PN heat stress and resultant oxidative damage.

Antioxidant

Besides its function as synchronizer of the biological clock, melatonin also exerts a powerful antioxidant activity. . . . Melatonin is an antioxidant that can easily cross cell membranes and the blood-brain barrier. . . . Melatonin's antioxidant activity may reduce damage caused by some types of Parkinson's disease. . .

There's been some success with tests on rats:

"Results suggest that oxidative stress contributes to appearance of pain in diabetes and melatonin, as an antioxidant, is effective in reducing the acute and chronic pain in diabetic rats."
