I think back to all those times I got water splashed into my nose till it burned really bad, and now, I understand why.
I just got into stage two, and I like everyone else have noticed a profound sense of self pacing. A strong feeling of how fast to go and that there is no need to rush.
I'm experiencing a lot of stretching on the soft palette. When my tongue pushing through it pushes the soft palatte down, putting tension on the tissues that hold it in place. I haven't been able to sit for more than a minute or two in that position, as I have just gotten through, but I can already feel the pull upward.
It seems as long as the tongue is in contact with some form of tissue it gets pulled up by the conductivity.
