HEad hurts badly today--too much csf

HEad hurts badly today--too much csf, evcen tho I try to get rid of it doing dahn yoga, but just too much fluid. Im having real energy issues too--sometimes I go thru literal "dead zones" of energy, and all i can do is lay in bed and sleep. I am sleeping better however, but tonight I think i am going to have to take tylenol pm just to get rid of mf headache
