Yanu... I've only been vaping for about seven months now. Some days extremely heavy and I have never experienced clogged ears.
Below is from a post in 2010 FWIW
Taken from Mister's post in the ECF Library:
The symptoms of nicotine overdose are clearer indicators of what is happening in your body than the symptoms of withdrawal. This is because nicotine overdose has been studied a fair bit. Nicotine withdrawal has not been studied nearly as much. What has been studied a lot is cigarette withdrawal which is a different thing - it includes no longer inhaling a few thousand chemicals, not just nicotine.
Symptoms of nicotine overdose:
confusion5,6,7,8
racing pulse, palpitations6,7,8
salivation, drooling6,7,8
agitation6,7,8
physical fatigue, weakness6,7,8
muscle twitching5,8
vomiting5,6,7,8
hearing or vision problems5
Just remembered it because like I said, the same thing happened to me the other day after I had been chain vaping. It could also be totally unrelate to vaping. Just monitor your nicotine consumption and see if it happens again. If it keeps up, go see a doctor.
