My bp has never been more than 110/60, so that's a possibility. The day I posted this, I flaked out at 9pm, DH went to brush his teeth and came out to see me fast asleep. I then slept for 13 straight hours (which I never do), I even slept through Charlie waking, crying, jumping all over me. The next day I felt better but still get the occasional headspin. I've got the day off on Wednesday so will see my Gp. Thanks Tracey, Christy, SP and ashnant.
