I'm hoping some of you may have found some solutions to this problem since the last posts over a year ago. I woke up last night to use the restroom and could hardly walk. I felt so dizzy and my head felt so heavy and the room seemed to be swirling. I was able to fall back asleep, but woke up to the same feeling again. I've never experienced anything like this. I have been sitting in the same spot on the couch all day. I have 5 children, one of which is a 1 year old. I have to drive kids  back and forth all day everywhere, and I'm really hoping this is gone by tomorrow morning. I just feel nervous that this may be something more serious. I don't have any other symptoms, no congestion, no headaches, normal blood pressure, etc. I am a very active person and even just ran my 8th marathon 2 weeks ago. Any suggestions or advice would be great. I need this to go away asap!
