Thanks for writing to us.
Basically to maintain the Biorhythm an individual needs to sleep for 06to 08 hours a day. Otherwise there will be definitely increase in blood pressure. The initial symptom of cold
sweat and dizzyness
could have been a result of sudden variation in BP as a result of lack of sleep.This is physiological or normal phenomenon.
You have not mentioned regarding whether you have passed urine when you went to rest room. sudden evacuation of bladder in such a situation will lead to gushing of blood to the urinary bladder
musculature depriving the brain from its blood supply for seconds as the urine passes out and the bladder musculature normals in thickness(In its maximum capacity the bladder would balloon out to store urine upto 750 ml almost obliterating its own blood supply if you withhold passing urine).The sudden crazy unable to stand and you had to sit up was due to a Condition called Micturition Syncope
. It is almost always Physiological or normal phenomenon.
Now you may ask why the condition improved after you have thrown up the Gastric contents.You have relieved the Gastro intestinal System from the work load and the blood supply was restored to the Nervous system. Again Physiological and it was untimely food in all probability.
I am giving you only the probability as I have only read the history and not examined you physically.
In both cases ie.,the root cause seems to be due to sudden change in your Biorhythm/lack of sleep.It does not seem to be due to quality of Food or water Per Se but due to irregular sleep/eating pattern.Kindly help yourself with normal sleep.
In the event of non improvement kindly consult a locally available General Physician for a complete evaluation.
Get well soon.
