OMG YES! I thought I was the only one who experienced this! I ended up in the ER, saw a neurologist, did a sleep study, the whole nine yards. Your description is spot on. I described it as my brain rebooting, a sudden falling/dropping, everything was off-balance but only momentarily. The doctors never found anything.
I looked into MS, vertigo, and a whole bunch of conditions. I was terrified that something was really wrong. After a lot of researching and review of my
vaping history I found what I think caused my issues. This is my own experience so don't take it as an answer to your problem.
I believe it was caused by two actions that happened at the same time. One was dropping my nic level too fast and too low. Six does not work for me; I need to be at 12-18. The other is that i think I built up PG to the point of an allergy with a 80/20 PG/VG blend. The decrease of nic and build up of PG in my system caused a cascade of issues all at one time.
Now that I've upped my nic and
vape no
juice below 50/50 (I prefer high VG) the symptoms have completely disappeared. This all happened about a year ago.
It's just my experience, but I hope this helps.
