I’ve suffered most of the last 30 years
I go to sleep almost instantly I hit the pillows but wake anywhere between 2 and 5 and struggle to get back off as my mind instantly starts working flat out.
Most people wake up and they’re groggy/sleepy for a little while, I wake fully alert and thinking.
If the OP is like this, I have a few tricks/methods that sometimes help me and may have already been mentioned.
First off, try not to let it bother you – easier said than done but try.
If you don’t go back off within a few minutes, get up have a drink, read some light fiction for half an hour and then try again.
Try to make sure you’ve cleared all the things that need doing before you go to bed, this is quite a big one for me, my ‘to do’ list is often the cause of my inability to switch off.
Worth repeating, don’t let it bother you, accept it for now.
