Try one shot of vodka before bed, that will knock you out!

Do you journal? It helps you mind rest. If you get it out of your system before trying to fall asleep, maybe you will fall asleep faster.

I read. I lay in bed and read until my eyes are so tired that they won’t stay open. Sometimes my head is actually nodding. It works for me. Maybe you should try it.

i know you said otc sleep aids don’t work..but have you tried benadryl? i know when i take it, it makes me pretty sleepy. I would take 2 of the 25mg and see if that works for you. If you are still against taking anything, try to use a relaxation technique, like inhale…wait 5 seconds and exhale…and do that at that pace until you feel more at ease…hope this helps!

I, too, had this problem; I work 16 hour night shifts and I had difficulties shutting off my head and leaving my work behind. I actually found an OTC sleep aid that worked and didn’t cause any problems with my asthma, residual grogginess or other side effects. It’s generic name is doxylamine succinate and it’s an antihistamine, found at Wal-Mart for only a few dollars a box. I urge you to try this before you totally give up.
Make sure your bedroom is quiet, dark and comfortable. Don’t read or watch tv in bed, anything you do in bed besides what’s supposed to be done can trick your brain into thinking that it needs to focus on something else than sleep at that particular time. Other than that, sit in a quiet room and read a book. It may also help if you take a warm bath, listen to music or drink a soothing, warm drink of your choice. Don’t watch tv or surf the net until you’re sleepy, it’s too consuming. Make sure that everything is done for the day and the only thing left is for you to go to bed. Read until you can barely hold your eyes open and then go to bed!
I found this to be the only thing to shut my brain off when I needed to sleep-the stress of work and the hours that I work shifted my focus from sleeping.
I hope I’ve helped and that you find relief soon, God bless.
