As with most of us here, mornings are definitely the most active. I usually get that first poo at around 4am and I dont feel as if I finally done until 6:30 which is usually when I leave for work. If I didn't have UC, I could get away with getting up at 6:30 get ready and leave for work in 30 minutes.
However with UC, planning ahead of time is vital, I don't have to be at work until 8 and my average commute is about 25 minutes, but I definitely enjoy the 45 minutes or so of quiet time. Plus, in case I have the unfortunate accident, that gives me plenty of private time to get myself going for the day.
It may be annoying getting up extra early, but it certainly helps because by the time I am done that last morning poo, I am usually good to go for the rest of the day.
