@Zoe7  I usually can’t sleep with any light, but my room here is next to my mums, and she gets a little confused during the night and can’t find the bathroom, so I leave the bathroom light on for her, it does lighten my room too.  

I have have been getting migraines often for most of my adult life.  I’ve stopped clenching my jaw which has helped.  

My breathing got a bit erratic before, I stopped concentrating on it while I was trying to relax my jaw, but I’ve started counting again
