@gaylea1 Great advice from @jolinda, and find it as quickly as you can. I had a Pre-syncope episode and knew I might faint so was heading to the sofa to sit. Before I made it out of the kitchen I went down on the tile floor and ended up with a fractured femur. Turned out it fractured because I now have rather severe osteoporosis which had not been diagnosed. I doubt it would have fractured if not for that but I’m sure I would have been quite sore.
Sometimes in the morning, if I didn’t get enough sleep I am light-headed. When that happens I will not drive even when it means skipping a water aerobics class.
