I have a question about mg strength for juice, I currently use 18 mg strenght but I've noticed that I've been vaping a little too much so I was thinking about lowering the mg strenght but I'm not really sure how low....not too low though because I still want the nic from the juice, enough to kill my nic fits....I expirenced a situation once where I was given a free sample bottle of juice that was 24 mg & I was vaping away like always & my head started to hurt like a headache....so I figured 18 mg was an ok strength & it is I was just curious if there's a safer level of mg strength so I won't run into the headache proplems again but with my regular 18 mg strenght just in case there's ever a day where I vape more than I realize....any help or suggestions would be greatly appreciated thank you in advance ECF....... keep on vapin' on
