Thanks for the good tips Mark! I will definitely follow it.

The insomnia came right after the blow to my head. But i do think that the fact of sleeping to much made it worse. For the past month i try not to nap, because i felt that it was indeed more counter-productive rather then helping me. My brain probably needs some more time to restore it's sleep patern after months of abnormal sleep pattern.

Also I'm switching to a firmer mattress tonight for my neck.

Good thing you said i should do light activities to increase bloodflow. I'm ridiculously fatigued during the day and that made me scared of doing any physical activity. Whenever i went for a small walk the fog would come back and i would feel weak. But what you said made me motivated to do some light activity. I'm thinking of doing some expose and recover with mild excersises.

And yes, the fatigue, insomnia, reduced blood flow, tinnitus are probably a vicious circle i need to break through.

Thanks Mark for giving me insight on my symptoms
