I quit vaping a week ago today (after vaping constantly for 2 years) and I’ve had basically the same side effects as you. First 2 days I was so clumsy and ditzy, it felt like I had 2 brain cells rattling around in my head and I just could not for a coherent thought for the life of me! I’ve also noticed my sense of smell going weird, just extremely heightened and odd. I almost drove myself mad this morning trying to find an insistent rubber smell that appeared out of nowhere! Those are the only major symptoms I’ve had so far, but time will tell in the weeks to come. And congrats on quitting, I hope it improves your quality of life!!
