Firstly: If you are a Suporn patient and you require a revision, for whatever reason, it is FREE OF CHARGE. This is an important thing to note. No other surgeon does this.
If you require a revision, you should always go to the surgeon who performed the original op (be it Brassard, Bowers, Kunaporn, Suporn, McGinn), as they are the most familiar with the technique used.
One of the most important things to remember about dilation is to relax. If you go into your dilation sessions with an attitude of 'Oh god this will hurt' or 'This effing sucks balls and I hate it' then you're going to be tense and it will be difficult to dilate. If you rely on drugs to get you through dilation, you will be exacerbating this and reinforcing you mindset that dilation is horrible.
I'm a Suporn patient and I'm in month 2. I've lost no depth (I managed to get back the 1/2 inch I thought I'd lost on the plane trip home). My current schedule is three times a day, 15 min per session. It's important to try and reach depth, then do dynamic dilation ('stiring the pot') for at least 5 min. The constitutes a quality session. Reaching depth and holding the dilator there isn't going to anything; you're trying to work against the contraction of scar tissue, which won't work if you don't do dynamic.
You should also be moving up to the Large dilator in the second month. I've managed to do this successfully and it doesn't cause any undue pain or bleeding.
To be quite frank, 90% of the patients who have problems don't listen to the surgeon and do not dilate correctly. The other 10% have biological issues that cannot be accounted for prior to surgery, and would have problems no matter which surgeon they went to.
