Hi Eroc,
Yes, drinking lots of water during the day and before going
to bed is known to help in some folk. Have you looked at
the vitamin D3 regime here?

Hoppy.

Hi
I've never fancied trying it. I would be up all night in the loo/john/dunny or whatever you call it.   

However, I would try it of course if all else had failed.

I guess it would cut down on night time hits if you never go to sleep!   

Before I peak, in the minute or two that first wakes me up - I want to drink water anyway. I have found that drinking water soothes me for a small amount of time until I am in too much pain to drink anything. But, I think chugging some water - around 16-20 ounces and then stopping whatever you are doing and doing squats and moving and getting your heart rate up and breathing deeply has kept me from getting the headache. Maybe it has a somewhat similar effect as the O2. But that stopped a headache before the peak, before it was too late and the torture really begins. I am hoping I never get another headache again, but that's my plan A for each attack from now on.
