could not sleep at night

Last night, I got a fever and could not sleep. This had happened for 4-5 days and the night before I had a few bottles of beer, making me sleep less and felt sleepy in the day time yesterday. I tried to sleep by closing my eyes, deep and long breathing and put my mind in Breathing, breath in, breath out, breath in, breath out....... Then I fell to sleep a while and woke up. I did it again and had a short sleep until dawn. Certainly, bad headache remained but I tried to eliminate it by exercise and washing some cars. In the late morning, I accessed e- mail and felt sleepy, then, I had a few minutes nap and now I feel better. I don't want to see the doctor, just try to make myself stronger and let it recover naturally. Hope that tonight, the condition will be better but now the fever still remains.
I always find a hard time of sleeping less at night. I think the healthy people who sleep long hours are the happy and lucky people. I used to watch TV., do some walking as meditation[ think of walking steps, left step, right step,..... ] or walking outdoor, or reading when I could not sleep. I thought that when I could not sleep, my brain was full of thinkng and was not in rest. I tried to make my brain in peace and sleep again. Never take any sleeping pills but I did it when I was young for many years and found that it was dangerous.
In buddhism, the principle teaches us to rest our minds, put our mind in what we are doing. That means, idea is the main machine of the body to commit sin or do merit. The frustration and hatred are the main factors keeping you awake. But for me, I have been stressed for working hard, worrying, and serving too many people for many years. This has made me a short sleep at night. Now I tried to sleep early but I wake up after a few hours of sleeping
I think you are lucky you are able to sleep at night everyday. This is a wish of the people who could not sleep. What is more in your life if you can lead the normal life and have good sleep everydays. Chavalvut
