My usual quota is the following:
- VMod Silver mini @work - 4ml / 12mg (by day)
- VMod Burrel Wood when having fun / travelling - 8-10ml / 6mg (in the afternoon, evenings)
- eBaron Dripper Pro / Bulli Smoker A1 @home - 3-6ml /6-12mg (quiet late night dripping)
So my daily intake is not enormous, but I could say: "substantial"

(around 10-15ml)
