Addicted to Checking Email?

Email is a great thing, but these days it is not uncommon for people to be addicted to checking email. What I mean by this is that often people will check their email even though they know it is not the right time or place. For example, if checking your email box distracts you from more important tasks, then it might be a sign that you are addicted to checking email. Some people if they cannot sleep at night they might get up and check their email. Well, that might not be a great idea because what if you will notice some important email from your boss and this will further prevent you from sleeping? I try to check my email daily, but I do it only once per day.
