Six days?  I used to work twenty one days in a row all the time.  Thats one of the reasons I burned out and got sick.  I do NOT recommend it.  Two jobs and one of them being 12 hours day non stop for 21 days.  The other 40 hours a week 8 hours a day five days a week.  And the bad part was, do to Clintons taxes, I LOST money doing it. 
That is really depressing.  I am going to go to bed now and suck my thumb. (J/k)  But bed does sound good.
