Difference between overdose and vaping too much

[cherrycakes]

I get really nauseous when I vape too much. Like I'm going to vomit.

Also every time I've tried the gum the nicotrol inhalers or any of that stuff I get dizzy and nauseous.
kind of like drinking too much coffee

For me first sign of too much vaping is ringing ears and feeling sweaty. If I don't drink tons of water, go breathe some fresh air, and stop vaping, I end up with a headache and sometimes see light sparkle auras. It usually takes about a half hour of not vaping to be normal if I stop before the headache. The headache usually lasts until I sleep or take Motrin, if it goes that far, but I go back to vaping slowly anyway. I've never felt nausea from too much nicotine or coffee.

I have a weak stomach. Also get jittery and cranky/anxious/shaky.
Same thing if I don't eat. Low blood sugar.
