I just wanted to update this thread to let everybody know that I had my root canal this morning and was completely fine. The shots hurt quite a bit more than they normally would, but once I was numb I was a-okay.
I am now on day 15 of my fast and things have been wonderful. In root canals past, (I've had 3!) the pain afterwards has been mind-numbingly excruciating, but this was a completely different experience. I had absolutely zero pain afterwards and I give full credit to this fasting experience. How amazing is that?! A root canal with zero pain!
I wish you all the the best on your fasting journeys and I hope that this thread helps out someone who was as lost and clueless as I was.
