Ness,

This is a diagnosable and treatable problem, I believe. There's something called a tilt table test. I had a friend (admittedly, not a very GOOD friend) who had problems like that. I believe the condition she had was called POTS (postural orthostatic tachicardia syndrome). It's a form of dysautonomia (and many believe RSD is too). I'm not sure how it's treated, but I know that there are medications that can help it.

Soo...the moral of this little story is to pursue this problem and attempt to erradicate it. In regular language, see a doctor and treat it. It doesn't have to be like this!!

Love,
Bets
