I know that O2 is just supposed to help while you're having the headache. Whats weird CHfather, Is that I had tried everything else and the longest i had gone in 10 years with out one was one month. I only had the tank for about 2 weeks and had only used it 10 times before they stopped. I kept it for 6 months thinking there was no way, But they never came back. I'm trying a sample of Emagilty tonight, Hopefully I can actually get 8 hours of sleep. Also, I will check out that anti inflammatory regimen!
