I bought green and orange because the first 4 Sole Source dilators map well to Dr. Chet's dilators.
I graduated from #4 to Green about 7 weeks ago. I moved on to Orange about 3 weeks ago. I am 17 weeks post op (I think - have to count again).
My regimen right now is
1. 10 minutes #1
2. 10 minutes #2
3. 10 minutes #3
4. 10 minutes GREEN
5. 20 or more minutes ORANGE.
I skip #4 as I don't find it necessary. I dilate twice a day rather than three times now but the extended times still add up to 2 hours or more each day. I am happy with my results, and my depth has not changed at all that I can see from immediate post op.
