I noticed the same thing. Very strange. I wonder if some of the other chemicals in analogs are synergistic with the nicotine effect..
That being said, if you don't drink enough water try increasing your fluid intake like RatRacer said. That's the first thing we tell people that have that problem.
I have noticed that I have been drinking a lot more water since I started vaping. Not sure if it's because I am more dehydrated, but it does really dry my mouth out.
Also has helped my allergies tenfold.
It's odd that PG would constipate, especially since its not really being introduce to the GI tract. Nicotine stimulates peristalsis, and I know that a derivative of PG is used as an oral laxative. Cant remember if its Propylene Glycol or Polyethylene Glycol....
To the OP, just curious, how long have you been vaping? It could be that coming off some of the toxins may cause this too. Or if some of the other stuff in analogs were helping you, your body might just be going back to its "Pre-smoking" mode, whereas you don't have the help.
EDIT: Its Propylene Glycol, same stuff as Golytely which is used prior to bowel surgeries/colonoscopies to clear out the colon. Didn't realize that... good news for the "It's the same stuff in antifreeze" argument
