Blood pressure question?

Has anyone else had problems with orthostatic hypotension, blood pressure falling when you stand up. For the past couple of days when I stand up I have felt lighted headed and like I was about to pass out. Last night I decided to check my blood pressure sitting, 120/77 and then standing, 86/76. No wonder I have been feeling this way when I stand. Has anyone else expierenced this?

DRINK MORE NOW. I had the light headed feelings too. And immeadiately everyone in my surgeon's & primary's office said I wasn't drinking enough. And now that I've increased it, but still not to the full gallon I never get the Light Headed symptons. So keep sipping all of the time. Water, Crystal Light (Walmart has their own brand and many more flavors) & any other zero calorie fluids count. Let us know how you do! Mike

yup yup.;.. exept mine was 86/42 sitting... go figure.. ohh well i figure ill live... lex
