After reading all these posts a few make sense.
Sore itchy throat, though don't know if it's PG or VG (think it's PG)
Coughing, mostly at night when trying to sleep.
Burping a lot (sounds disgusting, and is embarrassing)
Dry mouth
Passing wind
Head aches, pressure on my head (don't know if it's due to vaping, because I tend to use the vape more than what I would when lighting a smoke, and thus taking in more nicotine, or if it's a side effect of not smoking cigarettes/ roll ups)
Weird tastes in my mouth, one day everything i eat or drink, tastes salty, the next like metal, or I don’t taste anything at all.
My nose playing tricks on me. EG my partners vape smells really nice, though when I taste it it’s disgusting lol.
Sore tongue, as if someone split it in half and dry lips (change of weather maybe)
