My guess is in 5 years time. But as I mentioned, with family still in, everything is up in the air right now.
Welcome, welcome. I wanna say- a fade is a progressive action. Mine was pretty fast. Some people are even faster and able to walk away instantly and not be DF'ed. But if those are not the case, I hope you can still make some progress. You already fake some time. It would be great to get that M.S. monkey off your back. Maybe you could become irregular or even inactive and get fired. Maybe you could blow off some CLAM where you have a part and offer the poorest of excuses- "I took a nap after dinner and never woke up for the meeting."
With no wife and no kids, sure you want to keep your family. But is it possible to fade out also? Or to at least work toward being so irregular and undependable as far as meetings go, having no responsibilities but to sit there at half or less than half of the meetings and skip the rest of them? Instead of 5 years, you could be at that point in 1 year.
But if you don't do that, I get it. Good luck to you either way.
