Can you share what and how you addressed it? It might help others.
OK
A little background first I have sleep problems all my life, my Mother often said she had a 3 week old that slept through the night and a 3 year old (me) that had never slept through the night. For me going to bed became a hassle, being reprimanded for not going to sleep, threatened that Santa, Easter Bunny would not come if I did not sleep, I know kid stuff but that was serious stuff for a kid. When I got older, it was I was to nosy and would not sleep for fear of missing something. I know I drove my sleep deprived parents nuts. So early on the bedroom/bed became a negative place. I became a night owl after I left home for college, hotels were just places I stayed until sun came up.
Anyway how I got help, first I was sent to a sleep specialist and he had me read and go through all the steps the book No More Sleepless Nights. I cleaned up my sleep hygiene, only used the bed for sleeping. I try to take a few hours of down time before bed, no stimulation, often just sitting in a low light environment unwinding until time for bed, have a set bed time and wake up time. I also made changes to my room, since I had negative feelings about the room. I repainted, new bedroom furniture and mattress, blackout curtains and I also use background sound, I use winter blizzard sounds on Youtube. I just made the room a more positive space and comfortable, somewhere I want to be.
All this helped, but it is hard to maintain, if practiced 7 days a week, I would have no social life and nothing would done after I got home from work other than eating supper. I will also admit the slightest thing will throw me off, I am better at getting to sleep than I was, but staying asleep is another story.
I hope this helped, ask a question I will be happy to answer.
