I have done what you did in the past KH, but although I was able to stop in the moment, I ended up 'finishing the job' so to speak, within 24 hours - my brain had just become engaged in PMO mode and the momentum was too strong for me. I have to nail my fight in the first moments of temptation to stay sober - pretty much like metal22 outlines.
As for the question of do you reset the clock or not, I have a pretty clear view so far as my own thinking is concerned (but it's just an opinion that's right for me, and we are all different)...if the behaviour is unacceptable to you going forwards, then bite the bullet and reset the clock, otherwise there's the risk that you are giving yourself a subconscious message that that behaviour is OK, and therefore more likely to go there again.
Whatever you decide, it's all experience and learning and helping propel you towards your goal.
Thanks for sharing and good luck.
