I am a Chett girl - 6 months post-op.
After 6 weeks I moved to x2 per day, without any issues. Since then, i only missed 2-3 dilations (mainly due to socialising: getting in at 2-3am and realising that I have to get up at 6am to dilate so there is no point dilating at 3am :-)).
i can get to full depth within 5 minutes, on a x2 per day schedule (i do x5 minutes of 1, 2 and 3 stents, then x10 minutes of the number 4). After 12 months, I am going to try x1 session per day and see where that gets me.
Based on my chat with Chett girls from around the same time as me, some alternate between x2 or x3 per day, depending on healing and other personal circumstances, but NOBODY does x3 per day religiously, especially after 12 months.
Chett's schedules are really unrealistic. I had BA at the same time as SRS and, if I kept to the BA massage schedule and the SRS schedule, i wouldn't have time to work, let alone sleep or eat.
As an aside, I am really happy with the SRS result. I have a 100 per cent. success rate with solo orgasms :-)
