The closest thing I've experienced to what you describe happened to me a few days after I smoked my last analog. I had been feeling fine all day, then was suddenly hit with a headache and fatigue. I felt I hadn't slept in days. I went home and ended up sleeping for over 12 hours. I felt fine the next morning. It was the weirdest thing.
Occasionally I'll have some dizzy spells and get a mild headache, but that's probably caused by chain
vaping and getting too much nicotine. I'll just put down the PV for a while and make sure that I'm getting plenty of fluids.
vaping is dehydrating, so make sure you're drinking plenty of water. If you're feeling dizzy, hitting the PV isn't going to make it better. In fact, it might make it worse. My questions to you would be how much are you vaping and what level of nicotine are you using?
