You are correct of course, as there is no such thing as a failed flush. There is, however, such a thing as a pathetic and miserable flush, and I seem to have experienced five or perhaps more of these unwelcome guests!
To answer your question: I am unsure of how many flushes I have completed. I do know that all but two have resulted in physical sickness, and considering my post-flush state of overly-emotional confusion I am now seeking solutions to my many flush-based problems.
Rather foolishly I did continue to drink the potion even after I had a “gag” sensation about half-way through the mix. I usually drink it down in a matter of seconds, but after reading through many other posts I decided to relax a little…needless to say this did not work!
I am hoping that this multitude of suffering is for very good reason and that sometime soon I shall reap the rewards of persistence…
