I went back to work at 4 weeks, and it was fine. I actually had almost another week of the 4x-daily dilation at that point; I drove home during lunch to do a dilation for those five days I was working. For 3x-daily, it wasn't so bad; I did one in the morning before work, one right when I got home, and one before bed. I did have to get up about 20 minutes earlier, but that was the only change in my usual routine. (I went to Brassard, of course, so I had the same dilation routine you will - I think I had a slightly different schedule for which dilators to use and when, but the number of times per day and amount of time per session was the same.)
