Internet addiction

Sometimes I feel that I waste lot of time in front of computer in searching for information which is not required immediately or any time. Like an aimless wanderer on the road, I keep surfing from one page to another page by using the links available and realize later that I spent more than one hour without gaining any thing.
There are people who keep on checking mails, posts, tweets, etc frequently and some persons even have provision for alerts though it may not be so urgent to read whatever is posted. This leads to stress affecting the health. It should not lead to compulsory obsessive disorder as we had life when all these were not available and heavens will not fall if we do not check the information so frequently. One should allot only limited time say half-an-hour or so per day to check these things and proceed with other issues to have peaceful life.
Once, we went on holiday tour to a place by going through a river for two hours and stayed in bamboo huts overnight, roamed around the area in day time and returned back. For more than 24 hours we were without any connectivity with outside world and it is an experience. The tour guide alone carried a satellite phone.
