I was on mn recently in the small hours moaning I can't sleep and here I am again. I don't drink, I don't smoke, dinner was at 6.30pm so plenty of time to digest before bed. I haven't had coffee. For me, lights-out is usually 10 -10.30pm. I then flip flop around in bed until about 4.30am when I finally fall asleep only to wake again at 8.30am. It's not enough deep sleep and it's making me super exhausted and quite moody. I've had plenty of exercise today so you'd think I'd drop off pretty easily but no. What am I doing wrong?
