I work from home most days, but have a wife that wants nothing to do with diapers, so I am typically limited to two. Usually I start the day with a Dry 24/7, have lots of coffee, and then change into a lesser diaper, like the Tena Super.
I change after I get up and change again before I go to work. sometimes I don't have to change at all during the day. It depends on how wet I am. Sometimes I have to change before I go to bed and then I don't need to change after I get up.
