Anything that helps insomnia ?

For the life of me I can not sleep at night. I don’t know why but it’s always been like that. I’ll sleep 2-3 hours a night.

On my free days I’ll finally fall asleep during the day time but I can’t for the life of me wake up during the day on those free days.

I take over the counter sleeping pills but they don’t work to put me to sleep, and I’ll take Benadryl but I have a skin disease so it helps the itching but I take them every day to cope with the itchiness so I gotten immune to the sleepy part of Benadryl. If I go a while without taking them they will put me to sleep for 2 hours.

It’s driving me nuts! On my free days I want to go hang out with my friends or do something productive but I’m always tired.

I also have a low thyroid disease, but my last level checks showed I was getting too much medicine but my doctor isn’t going to lower my dose.
