(I've just read your last post, my post makes sense for your last post too, what you are encountering is probably a sign of progress, many practitioners cross the same feeling)
If you really crossed A&P, no doubt it will influence your practice. Time will tell. I suggest you read this excellent pragmatic and very inspiring description of the map by Ron Crouch :
http://alohadharma.wordpress.com/the-map/ to see what would be ahead. Usually, practice is more difficult and less clear, but it is very important not to misunderstand that this is nevertheless a sign of progress. You need to investigate, and (“try”) not be frustrated not to encounter and reproduce sublime states. Not missing our original goal : get detachment, whatever the feeling, it is impermanent and intrinsically unsatisfactory (one can say it could be good not to cross comfortable states in the beginning of the journey, because of the confusion it can involve).
Even if we tend to cycle from the beginning, the cutting edge nana tends to influence all our experience (while doing formal practice or not). It can be interesting to observe if fear can sometime be over exaggerated, or to observe the vibratory quality of our experience during the day (physical pain, anger, disgust, feeling down, etc.). If nothing is clear, don't bother. Just bearing in mind the purpose of the practice can help to progress through this part of the map. Whatever the step, we need to go out of the distorting prism to see what is missed. This is a natural process, it just happen with investigation (sometimes not consciously, without intellect reification). Your concentration seems good, it can help a lot too (don't bother too much if it seems to decrease, manifesting less clarity, just investigate). It can be very supportive to attend a 10 days Mahasi retreat, particularly if latter you feel stucked.
Yeah, I will let you know if I come to Paris, we can see that with PM.
P.S. : during A&P, notation and breath can be notably correlated. Tension (back and legs) can be the result of dukka nanas.
