I started on 18 mg and was almost drinking it as was getting through up to 20ml per day, changed to a dripper and was getting headaches off 18mg so mixed some 12 mg and found my consumption dropping to 15 then 10 ml per day. Still vape constantly from eyes open until eyes hard to keep open, and only go back to higher amounts when the mood takes me (or its a very nice flavour)
