I'm lucky on this one
You know people's bodies shut off the whole bleeding from the minge/reproduction cycle in cases of excessive thinness. My body is REALLY overzealous with this control so I'm immune unless I look like Kerry Katona after a pie binge. Which happens about every other christmas and involves me (i)looking like Kerry Katona after a pie binge and (ii) getting all two years of PMS at once and becoming actually psychotic,
and thus not likely to pull anyway.

Surely medical science could find something that does this to anyone but I'm not aware of such a product.
