I have had the absolute pleasure of playing the beta for guilds wars 2 and I haven't had so much fun in a mmo since burning crusade and a portion of WOLTK called ulduar.
There is a chance for myself and a lot of others to get highly addicted to this game and here is just some things you should do to keep your blood flowing.
1) Make your own food and drinks, don't get anyone to do it for you even if they offer.
2) Take a 10 minute stroll around the block, or walk to the food store if you have one close by at least once a day if you not currently employed. (Walk the dogs if you have)
3) If you currently going to gym or involved in a sport, do your best not to quit it for the game.
4) Make time for your friends and family still.
Please feel free to add any other suggestions.
