When I feel more tiredness then I able to take good sleep so I try to work hard on daytime to get tired.
This is perhaps the most valuable tip cited by Santosh and really there is no alternative for this. Hard work not only keeps us physically fit but also help us to get a good and sound sleep during the night...!
Most of the people have sleeping pills for sleeping as they won't get sleep but it is really unhealthy and shows side effects.Try to watch tv for more time , then you will get sleepeasily
