i've been vaping 24 for over 2 years now. i do get dizzy sometimes because i crave the nicotine so bad i don't realize when i'm vaping too much until i do get dizzy, i have to say i really enjoy it at one point in my life i was smoking almost 4 packs a day!!! now i'm down to the vaping the 24. i don't see myself stopping it at least for now, i think my meds make me crave the nicotine and caffiene as i drink coffee too, i don't drink alcohol so that's one good thing too.
