Let's see if I can make sense.
-Nicotine is weird, it can both cause and suppress respiratory irritation. Individual variation makes the effects unpredictable.
-Respiratory allergic reactions and respiratory irritation can be tough to tell apart because the symptoms can be identical. I suspect that the nasal symptoms like sneezing, runny nose, and watery eyes are most likely a result of irritation because, when they occur with allergies, the symptoms themselves are secondary to irritation caused by the underlying allergic reaction (read that last part again if you're confused, it does make sense). It's likely that if you have an actual allergic reaction (like I did my first time, I suspect a reaction to PG caused by a particular allergy I have), your throat will close and you will have an asthma attack. That's an acute allergic reaction to an inhaled substance. If nasal tissues react without lung involvment, it's likely just irritation. True, a less acute allergic reaction could cause just nasal symptoms, but the solution is the same either way: switch things up. Acute allergic reactions require more caution.
