Just wanted some advice..I have been vaping the same stuff for over four years. I use an Aspire Nautilus 5ml tank and an Istick power battery. My juice is apple from a local shop. I think I am a heavy user , my strength is 1.8. I don’t understand most of the technical stuff on this site. I am getting bored with my juice and set up and wondered if any one has any ideas how I can get some enjoyment from my vaping.
