to be honest i vape 9mg on the regular and never had a problem, the popo began when i got some 12mg juice. im back on 9 again and sleeping like a 4 year old baby.
Ok so I understand that nic levels affect sleep, proven by others and myself having resently vaped 12mg for the day into the night and sleeping really badly, Dropping down to 6 or even 9mg and sleeping better.
So the question is what flavours are we vaping and also are most of us dropping nic...
