Hi Suzy! Glad you posted. I can relate to the sleep thing. I laid down today at 1PM and the next thing I knew it was after 6 PM! I was out like a light. I woke up and both cats were sitting on my dresser staring at me!!
It's this heat...it just zaps all my energy. I still feel like I could go back to sleep but I'm gonna tough it out till at least 9PM so I won't be up all night.
I've not had the vertigo but my balance is terrible anyway and it takes me a while to get moving once I finally wake up.
I hope you feel better. Rest when you feel like you need to. I used to fight it but then later I'd feel even worse so we need to listen to our bodies. Right now, mine is telling me that I need a bowl of ice cream!! Tata for now!
