when i identify this state, sometimes i think 'i ought to take some vitamins & get some rest' and fall asleep; and when i awake, i may have a full-blown fever or sore throat or other malady...
not sure i'm describing it well, but IF you caught my drift:
do you ever have those same feelings after a b/p session? if so, please elaborate: specifically, do you attribute this to being malnourished or to having simply abused your body or ... ?
i don't normally have this feeling after b/p'ing and i cannot say that it's directly related to the severity or length of my b/p session, but i've wondered about this today and haven't yet read a discussion about it.
