I have not smoked in 48 hours- the first time in 25 years!! I have a problem. I think my prefilled cartridges contain to much nicotine. I am feeling funny- my head feels funny - I feel jittery. These are not withdraw symptoms. I have ordred ultra light cartridges but it will take 4-6 days to reach me. I really do not want to start smoking again is there any way to decrease the amount of nicotine in the prefilled cartridges that I have? Any help would be great.
