Are you suffering from G.A.S.S.? Yep seems to be viral and it affects the user and not the computer, hehe. GASS( Google Adsense Stats Syndrome) some smart people from the forums coined up the term. It is when you are constantly checking your Adsense Stats as in every 15 mins, every hour etc.. Its like an OC. We all know how it feels to see your earnings rise in the Adsense program and it is very addicting. Constantly checking can be counter productive. You could have finished some other more important stuffs.
