Annabelle, you are not alone! I too am having similar problems and have been trying to get some answers. I get these woosiness spells over me where I am lightheaded/dizzy like, hard to explain. Could sleep all day if allowed. I am going to a Chinese Medicine/accupunturist type dr. on thur to see if I can get help that way because I can't find answers other ways.
I take lots of vitamins/supplements that worked at first but now don't. I have lots of nausea too. I take zofran for that.
I hope you get some good responses I didn't get any with my posts
