5 isnt that excessive,Ive seen hardcore vapers going through a lot more than that chain vaping on 6 volt devices. If you notice any adverse effects then stop but as long as its keeping you off analogs go for it.
I know it's probably been asked many a time, but if vaping 5 Ml or 6Ml would you say that is way too much to be vaping per day?
It's not so much to do with the nicotine level I am using, I just love vaping and the flavour I am vaping.
I easily go through 5mls a day on my days off, and when I'm trial vaping probably more than that. I'm not sweating though because I'm sure that when I settle down to my 4 or 5 favorite blends it will taper off, as will my expenses.
