Thanks guys, i have loads of liquid that's 12mg so at the rate i vape atm that's gonna last me a good while, when i am in bed i wake up quite often through the night and vape like it's going out of fashion but through the day it's totally different. Don't get me wrong i enjoy vaping especially if it's a favourite juice but it's like my head is saying i don't need it but my body disagrees , i will attempt to drop down to 6mg , last time i tried dropping from 18mg to 3mg and quite honestly struggled at 3mg so popped back up too 12mg and was quite content, maybe my body is saying look you don't need 12mg. What i can't work out is why through the night i am vaping so much but not through the day, maybe it's because my mind is more occupied during the day, saying that my head never switches off, when it's quiet i think about stuff more accounting for me waking up and vaping.
