Thank you all so much... I think that it was
* Not drinking enought water (water made me want to puke - bluddy m/s)
* Not eating enought (again bluddy m/s)
* Being 'tense" as I was trying not to vomit all the time. So I was holding my shoulders near my ears!

What helped:
* Massage using those accupunture points (by a proffessional) within 10 mins , 90% of the pain had gone (it did come back that night but is gone today).
* Cold wash cloth on head, dark room, no noise, no lights
* Drinking water (flavored with cordial if I have to - need to get it down!)
* Streching my neck out

I think it is just a part of my body 'adjusting', so much is gong on that my weakest point (my back) got tense... If anyone is having headaches I higly recommend seeing a trained massage thearpist who also knows accupunture... I only did the $15 for 10 mins - so it does not even need to cost you a lot of money!..

FYI: I smashed my head open this morning on the car door and while I was getting stiched up the docotor said "gee you must have a massive headache, and I said, actaully this is the first day in two weeks where I have not had a headache - this pain is nothing compaired to pregnacy headaches!
