I was a filter-less tobacco smoker. I started
vaping 18 mg and with that I seem to want to chain vape. In the mornings with my coffee I vape 24 mg sometimes as high as 28-30 - just to wake up and feel that i've got enough nicotine. I'm using a Riva SE 3.7 battery and 2.0 ohm atty.
I plan to try a 5v soon. I understand at higher voltages and lower nic strength you get the same feeling/effect as with higher nic. I may be able to cut down my morning nic levels to 16 and still get the 24 mg feeling. - so the voltage you vape at comes into play big time here. This is something not a lot of people talk about.
As far as adverse side effects, I have to cut down late at night and be sure i'm not
vaping anything over 18 or I have trouble falling asleep. I suppose this is due to nicotine being a stimulant.
