Baclofen is a drug dr jay goldstein use to recommend for many cfs patients, i have found it helpful for increase sleep depth and good for headaches, possibly help with brain fog, cheap and available by 4rx under muscle relaxers. If your after increase blood flow to your brain, this may seem strange but small doses of viagra as in 1/4 of a tab ie 25mg can increase circulation in the brain as well as other body parts, its a strong vasodilator, so need to be careful if u have low blood pressure. I had an ongoing headache i couldnt get rid of after trying many treatments, i tried a small dose of V and it went within a few minutes and cleared my head, i found it doesnt work all the time but does help clear your head from improvements in circulation. if your lucky sometimes these online pharmacies through in trial samples with your order.
cheers!!!
