I can't believe the difference. Stopped hurting. And am sleeping normally again. I think it is because I am keeping the house a lot cooler now. My allergies kicked up for a while but we had a frost and even those are settling down. Still fighting some brain fog. I sure wish there was a good way to just make the brain fog disappear. That really bothers me more than just about anything else. I can put up with the pain - but its hard when I can't think right. Whatever - it is great.
