It all started with my falling down while mowing the yard.  I was unable to get up even though I was not dizzy and could feel my body.  I remember thinking I wasn't sure which way was up.  After a few minutes, I recovered and finished the lawn.  A few weeks later I fell in my garage, hurting my elbow, and decided to see my doctor.  He sent me to a neurologist who said I had nystagmus, easy to fix with some barrel rolls.  Nine months later I was cured.  When I wasn't, I saw a heart specialist who gave me a tilt table test, which I failed.  From prone to about 45 degrees, I passed out, which I never did before, and it felt like I was being electrocuted.  Several specialists and 3 years later I got the MSA diagnosis.  Today I struggle getting into a wheelchair so I can relieve myself every few hours.  I'm sure I should be drinking more fluids but that just means going more often.  I last now 1-4 hours (caffeine is not my friend) and can go as long as 8-9 hours at night.  I don't dream I have this condition so when I wake I have to remember I don't need to rush off somewhere or I can't just stand up to go to the bathroom.  Sobering.
