So it's been a week on the botox and the saliva is certainly better from a quantitative standpoint if not from a qualitative one. By which I mean there is definitely less saliva but I still need the bib, still choke at regular intervals and still can't lie on my back. There are a couple of benefits I have noticed, though. I can hold my head upright for longer before I have to lean forward and dribble. And I have less trouble choking in bed. Which are no small benefits.
So a cautious thumbs up to injecting your mouth with poison.
