My side effects have been a bit different.
Some are pure in my head habits. Like trying to head outside to smoke every hour or so. Stopping at the door and thinks "No wait, I don't have to do that anymore." Another was fishing in my pocket for a lighter that wasn't there.
Some have been odd like the wild weird dreams that would often wake me up 6-7 times a night for the first week. Those have stopped thank god.
Most of my symptoms could be traced back to one thing. Dehydration. I had to make myself learn to drink tons of water. The most annoying one was needed to shower 3-4 times a day because my skin literally HURT from my sweat being so acidy. I mean sunburn all over my body kind of hurt.
On the high side my allergies have virtually vanished. I have only had to hit the benedryl ONCE since I started vaping and that was after a really big hit of fried atomizer. Insta sinus headache.
My sense of taste is starting to come back which is both a blessing and a curse as I discovered I was really OVER SEASONING food. I live in Louisiana our food is stoute to begin with. Over season it and you hit OUCH pretty fast.
I haven't hit the massive coughing yet though I read that that one hits different people at different times. I will both hate it and welcome it when it comes. Its miserable but if it get the crap out of there great.
Emotionally outside of a sleep deprived first week I haven't had any problems. If anything I have been less prone to depressive mood swings.
Everyone reacts differently is really my point. If anything happens that really concerns you (like my skin did me) see a doctor.
