No. I do not sleep with my mobile on the bed. Instead, I finish all the things I want to do on mobile and keep it away from my bed. One reason for doing like this is I do not want any disturbance once I go to sleep. As you know, a sound sleep of at least seven hours is essential for our well being, I ensure that I do not miss it.
Moreover, what is the need to have your mobile by your side, when you go to sleep? Just like us others will also be sleeping during those odd hours. Therefore, who is going to call us at that odd hours? Similarly, I see and use internet as much as possible during the day. So there is no necessity for me to surf the net too after eleven or twelve in the night. I think, we have to use the mobile in a prudent way for our own betterment.
