For me, it did not stop yet; it changes however very much in duration and intensity. By now, I got used to it and know quite well what is going on in the body. I read that others had this for years, so I do not worry about the fact that it continues either, as long as I have the impression that the “body re-formation” is continuing, and that the energy is not going in circles, does not get stuck.
It started in April 2014. After a few weeks of shaking on the cushion only, I experienced a few very intense shaking “events” at night – woke up in the middle of the night because the body wanted to shake violently. I mean REALLY violently, with real big and very pronounced movements.
Luckily, (a) I live alone so nobody was around to panic (b) by the time this happened, I had read a bit about this on the internet, so I did not worry, submitted to the process and got myself out of the way as much as possible. On the contrary, I was quite curious about it and watching it I was very much impressed how skillfully the body did its workout without any assistance and/or intention from my side. These events also used to end in a deep sense of relief and relaxation, and I found them very beneficial. Maximum duration was 1 hour, minimum 20 minutes.
Berceli give some nice information. His book is interesting, too, in spite of the many repetitions (it might be shortened to one third of it). I like his approach better than others because he does not force it; he advises just to submit to it when time and situation allow for this.
I also found this short video by Shinzen Young interesting:
