Did you guys see the posting from an adult lady a while back, that was talking about her DHEA levels?? I searched for this (at snap.com) and came up with a lot of interesting info. I seem to remember one of the articles claiming that if you don't have enough of this growth hormone (which is also produced by the adrenal gland), on of the side effects could be severe headaches - even migraines. Might be something to check into; I don't know much about it - yet!! Good luck - headaches are miserable!
