So.... Last night I decided that I would do two of the 10-minute trainer dvd's that I have, instead of walking.
I was so pumped up. I had my music on...nice & loud... I was full of energy and dancing and running around the condo. I kept running up and down the stairs to get things.
Then I popped in the DVD and started the workout.
I was breathing deep and focusing on my posture... at some point I started to feel lightheaded. So I drank some water and realized I was REALLY light headed.
I decided to sit down for a minute on my bed because my head was spinning.
I "woke up" on my floor. I could feel my eyes fluttering. The loud music didn't sound so loud. It sounded very muffled. I sat up and felt delirious. I went to the bathroom and splashed my face with cold water for a minute or so...
I sat in the chair at my desk and was kinda falling in & out of consciousness. I threw everything off of my bed and lied down...and fell asleep. I was in and out of sleep for about an hour & a half.
When I woke up I felt fine. I lied in bed for a little bit before getting up and taking a shower... that was a scary experience.
