My advice to you would be to SLOWLY ease into this.I know one strategy is to take one of your vacation weeks and pretend as if you are a full time pro player and see how you feel then(i.e. wake up at noon or whatever and devote the full 5-8 hours a day for that ENTIRE 5 day week).If at the end you feel ok then perhaps slowly transitioning into the pro lifestyle would be the best approach(and less stressful for you and the missus).
