Sometimes I can sleep pretty well and then at other times, such as right now, I don't, waking up all the time or being 1/2 asleep the whole time and feeling weird (?)

I have a ritual I have to do or get upset (?) like Living_Dazed, have to have a fan on but it has to be the same noise all the time, certain sheets and pillow case, complete darkness.

If the fan is not on I feel like going berserk, don't know why.

My concussion was over a year ago, hope you get some good sleep soon
