[QUAD-L] low blood pressure

[Alice]

I know that when I have sleep deprivation I'll blank out and have to put my 
chair back; my blood pressure is sometimes as low as 80/38.  I want to know if 
I need a certain vitamin or mineral or what can I do to avoid this problem.?  
This is Mike I'm a quad C-5inc, 46 yrs old.  Any feedback would  be 
appreciated.
