Re: What is happening!!
I think what you are describing happens to me as well. The days that my allergies are really bad, I am just miserable and I feel very out of it. But it may not quite be the same thing because it's constant, not just when I'm bending over. For example, yesterday, at work I had a headache and a lot of pressure behind my eyes the entire day, despite taking extra-strength Advil. And I felt really spacey the entire time. I don't even remember most of the conversations I had and could just feel myself losing my train of thought when I was talking to people.
I'm not sure what causes it, though.
I think taking vitamins is a good idea in general, but I don't know that it will cure it. I take a vitamin daily and it has no effect on the days that I feel like that.
I hope you feel better, though, and if you find anything that does help, please post about it.
