If you need to, can you run down to a convenient store, and get a disposable to get you through the night or a couple days til you get the stardust? I haven't used the tank systems so am not really familiar with them. But here are a few basic things.
Vapor's tongue: It happens, suddenly everything you've loved tastes really nasty. I usually vape a super strong peppermint like vapedude's ice ice to kick start my tastebuds again. You can get a free 10 ml sample bottle using the code fbfree they do about 15 a day, it resets sometime around midnight, give or take a couple hours. So if it doesn't work, try later.
Use alcohol and qtips or alchohol prep swabs to clean the battery connection and the threads on whatever you're attaching to the batt connection every day or every other day. Carbon or something black will build up on those and that can make juice taste bad.
With the stardust or vivis etc, definitely clean em and dry burn every few tankfuls. I also always rinse after a dryburn to get off anything that might have burned off, but didn't fall off. You don't have to wait for the them to dry again, dry burn, rinse, blot wicks with paper towel, assemble, fill, vape. Hope you got the replaceable stardust, they're a million times easier to clean and maintain.
