I put in around 4-5 hrs per night after work ( I work from 4pm till 1am so no one is awake but me

) and on the weekends it will be in the 10 to 15hr range. So I guess that is like what 30 to 40hrs per week. I did not realize it was that much. Good thing the wife doesn't know or my arse would be in abit of a fix.
