I just started vaping like 4 days ago and I have not smoked for 4 days. At first everything seemed fine, no big issues but I craved real smokes pretty badly. So I would just vape a bit more to cover the need. Now day 4 has rolled around and sort of out of the blue I am starting to feel pretty sick. Nausa and stomach doesn't feel to hot. I have read it may be my nic mg, but it's weird it never affected me at all thee first 3 days. I know this could be withdraws from real smoke, or is this normal? Like I went form smoking 44mg of tabacco products to 24mg juice (approx 2ml a day, so I doubt it's my nic levels. I smoked pretty heavy so would this make sense or what do you think? Did any heavy smoker have symptoms like this?
