not a DIY... but I love ACB from nicoticket .... sadly all the best creme flavors including that juice have the nasty chemicals in there that cause popcorn workers lung or w/e its called

so I buy the occasional bottle from nicoticket instead of stocking up on the supplies to make it so I limit my intake...
3cents a ml and no nasty chems with my typical DIY stuff ... or over 60cents a ml and i know its got some nasty ingedients

my will power is too weak when I don't break it down monetarily
