I haven't actually tried it yet because I haven't needed to; the pressing my forehead into my hand thing seems to prevent the tension headache stuff, at least.
However, your reminding me of this has made me curious so I may need to try the experiment anyway. I wonder if I could wear chemical patches while bouldering?
