Congrats!! Ive done H and that's a wicked one. You are doing great.
Try melatonin. I started w/ 3 mg but doc said I can go as high as 12 mg. I don't find it to be an amazing thing for me, especially when I'm coming off pills, but it does work a bit.... And for some people, they swear by it. It does relax u. Don't expect it to knock u out. Well that's not my experience. But keep your mind open to it, as drugs affect people in different ways. My friend takes itvand is asleep in an hour. It is worth a try before going the script route.
If it doesn't work for you, give it a few days, then perhaps see your doctor. You are doing so well, you don't need the insomnia to derail you. And remember, as Phoenix said, it really does take time for your body and brain to recover.... it sucks and it's not like you deserve to torture yourself .... just know that it's normal.
Keep us posted!
