I gave up the real cigs over 18 months ago and went a bit overboard with stocking up on the liquids - I wanted to try them all.
Anyway, I actually gave up the vaping about 6 weeks after I started (and stayed of the real cigs too!) but after all these months I suddenly wanted a smoke again so I've dug out my old kit and juice so I don't go for the stinkies.
I know some juices need a bit of a steep and darken in colour over time, but how long do juices last in the cupboard? I've got a custard which was a nice light caramel colour when I first bought it but now is very thick muddy almost black.
When I returned to vaping after a 2 year hiatus, I was using my old juices - some home mixed, some bought - which were all over 2 years old - they seemed fine, although I've now stocked up with more recent juices!
