Hi LadyBelle - I don't know if we are thinking of the same headache trick - I learned one that is from reflexology - press the thumb of your right hand into the middle of the palm of the left hand - this really works although the headache resumes when the pressure is released.

I saw a woman on TV last night doing something called "sex yoga" supposedly you can control almost anything with it - she claimed you can adjust your menstrual cycle and use this as either a birth control technique OR a way to increase chances of conception - no doubt she has a position for constipation relief too
