Last night, after standing at the bathroom sink for approx a minute and a half, I was suddenly overcome by dizziness, breathlessness, and my vision filled with big black splotches. I quickly grabbed my rescue inhaler and sat down, and then I took two hits from my inhaler. I really didn't want to faint in the bathroom, so after that I sat on the toilet for a moment to try and catch my breath, I made my way back to my bedroom. I only walked about ten feet, but all of the previous feelings came rushing back, and I barely made it to my room. I collapsed on my bed and I lay there panting for about five or six minutes before I could get under the covers, and then I fell asleep shortly after.
This is not my first experience with feeling dizzy, and not even my first in the bathroom, but this was the worst experience I've had so far. I have narcolepsy, chronic fatigue, and asthma. When I google the symptoms I see a lot of stuff about hypotension, but my attack didn't occur immediately after standing up.
