In my experience if you dehydrate yourself to diminish the drool you will have all sorts of other problems during "play", everything from muscle cramps to a trip to the hospital can happen. So I do not reccomend that even if its the only thing that worked for me with this paticular biddy (I learned the hard way).

(If anything I drool less when I am in subspace lol so I wouldnt worry about that as an indicator smh lol)

You can allways try to swallow it or suck it back up if you can get a good seal with your lips on the ball but as you probably allready know it makes it awfully easy to gag or get into hysterics from breathing dificulties and anxiety when the drool thickens and you cant swallow it or it gets lodged in the back of the throat.

The safest thing is to go ahead and let the drool flow .
