Wow, what an interesting question, cadence.

i guess my off-the-cuff answer would be no, since i understand subspace (in my more clinical, vs mystical mode) as an endorphin thing: pain + fear + arousal = happy subspace brain chemistry. At least, that's my personal formula...different for everyone.

Sometimes said endorphin levels drop below normal before returning to a comfortable baseline, and that's subdrop, as i define it. i feel all of the things icey described: weak, weepy, confused, trembly, depressed.

Standard aftercare ************s of food (pretty sure this is the true purpose of chocolate), sleep, wound care all help bring chemistry back into balance. A warm bath and a cold sports drink can work wonders.

From the emotional standpoint there's no substitute for a caring partner who knows you well.

Having said that...not always having this kind of partner doesn't necessarily keep me from playing.
