Took a yoga class today....and so far so good...no headache all day long... I feel tired but that's because I had about 4 hrs sleep last night...I'm forcing myself because I want to get back to normal sleep pattern (meaning sleeping at night). Concentration seems ok.. Focus is fine...no other complain able symptoms... I was a little concerned too because there was a lot of head down positions...alot of blood flow to my brain...lol. I also had my chiro..adjust my neck and back today... Now to lose the 13 lbs I gained thru this nightmare....lol
