what is the fastest transit time can possibly be? can I be empty yet? ate dinner at 7.30 (ish) runs started about 20 mins later have been on the loo for most of the last few hours.
is the food I ate this evening out or just much further up the system waiting to get me out of bed in a rush in a couple of hours?
(I guess I am asking if it is safe to got to bed'?)
