Problems with sleep

I would advise sorting out your sleep schedule:
- Go to bed at same time every night
- Wake up at same time everyday including weekend and even if you haven't slept much the night before.
- Don't use any devices with blue light e.g. phone / computer etc at least 2 hours before going to bed.
- wind down so that your relaxed before sleeping.
- Do exercise in the day so that you feel tired at night. Don't exercise less than 3 hours before sleeping.
- Have a diary nearby so that you can write any thoughts that are preventing you from sleeping

I have similar issue to you whereby I wake up after 2 hours of sleep because of a sexual dream and then I can't go back to sleep because the urge is too great. However I push through it and the next day I can sleep better.

 

I have a sleeping issue also. It's very difficult to fix.
