Home Insomnia Cures

Any home cures for insomnia !?!?!?

So here the problem, my friend has trouble sleeping. He is going on as 4 days without sleep and im really worried about him. He tried to take Benadryl and it did not work. He tried to listen to music. He tried to read a boring book. So if anyone has any ideas for a home remedy as one that nearly everyone can do without having to go out and buy things to make it. I really appreciate any advice much. so thank yall. Nox is a lot on his heart. and I mean A LOT. He has talked to me for a bit and then tried to sleep again. Im not sure if it worked. but even talking sometimes ya still can not sleep. For no matter how much you talk. Some things are not going to disappear. So I'm looking for some Remedies. He told me he still could not sleep he would call me back, so im just trying to get some ideas ready. I would have suggested a nice warm bath or shower to him; but he has been awake so long I'm afraid he would fall asleep and injure himself if not worse drown.

According to http://sleepdisorderstalk.com/insomnia/vitamins-for-your-sleeping-problems , Lack of vitamin B and iron can cause insomnia, can you advise your friend to then set the levels of these nutrients up by taking supplements or eating foods rich in vitamin B and iron. I have to say that four days without sleep can pose a real danger to his brain. regenerates the brain while we sleep, and since he does not so, the brain does not also do what it needs to do. I'm sorry, but I do not think a home remedy would be enough for his case. He must either see a doctor or take a pill.
