You need to bring your BP up, otherwise you may end up hurting yourself or others. Orthostatic hypo-tension mainly happens in older people, like >85, due to weakening heart muscle and taking meds. Please seek medical advice.
Drinking more water and increasing salt intake may solve the problem, but do it under medical supervision. Alcohol slows down the sympathetic system, so a slowdown in heart rate and the resulting BP.
Got it. Used to happen to me growing up..nothing serious...the falling and temporarily lose of consciousness happen to me twice i think 2 or 3 yrs ago...all the time...i had been drinking in my couch later at night..and gone for a pee.
