Help. Mystery of why I continually pass out?

It was interesting to me when you talked about how things help and then stop working! UHG! I just couldn't understand why a medication would help me for a few weeks and suddenly just stop working, this has been going on for years and doctors would just give me a puzzled look! I was diagnosed with Dysautonomia a few days ago. It's nice to know there's someone else out there that knows what I'm going through. I was told to increase my water intake, I'm really trying!!! Does that help with your fatigue? I know it does but hoping it will make a big difference, wishful thinking, lol.

I was told by a dr, that when the medications stop working, that is because your body has normalised, so, you dont really need to take it anymore, so maybe you can then switch to lifestyle changes.  I get fatigue because it affects the sympathetic nervous system, which, is the fight or, flight system, after this, it then  affects the parasympathetic system, which is the rest and dijest, this is triggered naturally after you have been under stress, but with dysautonomia your not in control of the adrenaline it just happens because our nervous systems malfunction, so, with the fight or flight one, everything quickens up due to the amount of adrenaline in the system, i lose weight, muscles go weak, fast heart beat, dizzy spells, cant stop weeing, so, you lose blood volume and dehyrate, i become exhausted because of how overworked my body becomes, inititally it was like having PMT all the time, so, first i rest, and yes drinking water, along with being very liberal with salt in my food really helps as soon as, i feel as though im coming out of it, stop with the sleeping and rest, otherwise you will go the other way, and decondition yourself, that means your body clock, and sleeping patterns have gone out of wack, makes you  feel extremely drowsy, basically you have done too much sleeping and resting, so, you need to exert yourself then, you get the opposite to the stress which is, the rest and dijest symptoms, thats when your body slows down makes you feel lethargic, so you know then to exert your self more, your muscles become weak, you pool blood in your abodomen and legs, but because your stomach muscle are weak, you cant dijest your food properly, then when i stand i go to pass out, i feel all my food is in my upper abdomen, and if ive eaten too much, i can vomit whole pieces of food back up, i feel like my body is trying to push me to lie flat, which, is what i do, as it helps food go through the system better takes about 30 mins of lying flat, but once all this settles, you should find your back to normal until the next trigger, its general an out of balanced nervous system and anything can knock it off, and whilst i have vasovagul syncope, its not just passing out, its much more because of what it affects,  it causes chronic fatigue, slow dijestion, and spikes in sugar levels, its controlling all this once it gets started, the vagus nerves are responsible for sending all the messages through neurons to the brain to signal things to work that we dont know are happening, there automatic mainly.   The sympathetic and parasympathetic systems,  are in the spine, and its a case of the messages getting mixed up, so for example, you eat, messages through neurons from the vagus nerves, it travels to the brain to say, shes eating send out a certain amount of insulin, message goes in wrong, as a result brain can send in too much insulin, or, too little, so my sugar then drops, or, goese to high, depending on which system its affecting you at the time,  so, your coping with this as well, either things run too fast, or to slow, its the in between bit your trying to stick with, sometimes you get it right and sometimes you dont...................its a complete bummer, i was born with it, but only diagnosed feb 2016, started going the drs with it myself when i was 17, so, its taken me 40 years to get the diagnoses, and i started with my symptoms aged 18 months, started with convulsions, then whilst growing up, noticed i couldnt eat sugars, and started blacking out when i was at high school, then PMT symptoms when i was 17, but it wasnt really PMT, the convulsions are caused by low blood volume, and low blood pressure, so, there is not enough oxygen int he blood so you can either convulse or, pass out, over the years ive done both.
