I have been vaping for about 2 years and 5 months now

happy with twist/spinner and mini vivi novas,
found my 3 or 4 favourite liquid flavours,
daily dosage: about 2-3 ml (with 6/9/12 mg/ml depending on my mood),
general health, tasting/smelling and energy level have improved rapidly in the first few months (started running too)
today vaping feels totally "normal" and intuitive to me, never experienced any cravings for cigarettes, never regretted the decision to switch!
