Vacations

Ok... I know everyone probably needs a vacation. I know that I should probably be no different but I can not seem to disconnect from work. I continue to check my Black Berry for new mails. I send out short emails to co-workers for updates on issues. I think that I prefer to take long weekends...start on Thursdays go back to work on Monday. Does anyone else feel the same way? I mean...I am probably the exception to the rule. Does anyone have advice on how to actually go on vacation without thinking about the office? I would really prefer to relax and not think about anything but relaxing.
