All day, every day, for however many days the banner says.
Though for the first time since i started vaping, i stopped vaping Bobas and vaped Nicoticket juices for a month (enjoyable), when i went back to Boba's it took awhile to get back in the swing of it.
I am a pretty big fan of ACB though, but i'm still on the fence about the whole diketone argument, so ill stick with Bobas till i'm forced to change by moving to 3mg (since AVE refuse to make it).
