To be honest, I think my energy level may have taken a slight hit, but I've adjusted. I have 2 kids and work 50 hrs/wk, but I don't let it slow me down. Biggest difference is I used to be able to really push myself and more easily get by on fewer hours of sleep, and Icant really do that to myself anymore. Like where I used to routinely get by on 6 hrs/night, now, I can do 6 hrs a couple nights/wk, but I need 7-8 on the others to keep up. I couldn't function well with pouchitis though, so needing more sleep is a reasonable tradeoff for me.
