I only started 10 days ago Vaping, but as my throat is sore I have stopped for the last 3 days and using patches and still suffering heart burn etc... Hopefully it does not go on too long, sleeping patterns are all over the shop.. and I think Farting etc are withdrawal symptoms.. and I would not point the finger at PG as I see loads of peeps do here.. At least wait a month or 2 to decide if PG is giving you side effects, as most withdrawal symptoms should of be out of the way. Agree ?
I think the sore throat is at least partially dehydration. I saw a lot of people talking about sore throats (and dry mouth and dry skin) before I started vaping and have experienced it myself. Mine went away when I made a strict rule: if I'm only taking a puff or two, I owe myself a sip of water soon, but if I'm sitting down for a "vape break" then a full glass of water has to go with it. That's had other benefits: it seems to help with a lot of smoke-withdrawal symptoms, like the awful acne I'm getting when I forget to hydrate.
PG is hygroscopic - it grabs on to water molecules. Otherwise, we wouldn't get vapor; the "steam" we substitute for smoke is pulled out of the air by the PG. But it stands to reason that the PG will also do the same thing to the water in our mouths and throats (or at least that seems reasonable to me) and a dry throat is an angry throat. So putting water back in sounded like a good solution (ha) to me, and it seems to be working so far. (Then again, it might just be that pulling in hot air of any kind is irritating, and going analog-free lets our throats heal enough to start complaining again about the lesser irritant of the vapor.)
On the bright side, I've seen this dehydrating effect offered as the explanation for the demonstrated antibacterial and antiviral properties of PG: maybe it just dessicates microorganisms to death. So vape away, drink lots of water, and don't be afraid to hug a friend with a cold.
