I've found, that even with my favorite juice - USA vanilla from goodprophets, I still need a break every few days. Originally, I thought I could find one and vape nothing else for eternity, just like analogs. I think it's more like food. A person just can't eat the same thing day after day and not get tired of it, no matter how much you like it. I need to switch to another juice every 3 or 4 days, for a few days, and then return and enjoy it all over again.
