Interesting thread because in December I woke up for 3-4 days straight dizzy. Soon as I got up I had to sit back down for a few seconds before the dizziness went. After 3-4 days it went and then recently it has happened again. This week I have had 2 episodes of dizziness, this time one was at night in bed and then the following morning I had it. I need to go get checked out for sure, not sure what is triggering it.
