I've been trying to sleep on and off for almost 3hrs now. I look awful, you should see my eyes! This isn't that unusual for me though unfortunately, I often struggle with sleep for no apparent reason. So far I've tried intermittent periods of laying in bed, reading, having DH read to me, sitting quietly with a cup of herbal tea, did a facial skincare routine that I decided I was too tired to do when I initially wanted to go to bed, lavender moisturiser, Mumsnet (I have a blue light blocker thingy), put laundry away, did some tidying up...still awake. I will be lucky to get 5hrs sleep tonight possibly less depending on how long this goes on/when DD wakes in the morning/whether she wakes in the night etc. I know I will feel and look awful tomorrow 
What do you do when you can't sleep?
