Don't despair, prepare! I doubt anything significant is going to take place w/in the next three weeks. You'll probably have time.
I don't know what nic level you're used to, but the other thing you
could do, if it's a higher level, is start backing if off to reduce the amount needed to achieve satisfaction.
Assuming you're mixing your own, that'll make whatever nic you store last longer.
E.g.: I quit smoking over nine years ago. I vaped three years ago, and recently started again. Not because I
needed it, so much as I enjoy vaping. Both times, then and now, 3mg could/can give me a nic buzz--that's how little it can take. I don't even really
need the nic, any more, but I do find it improves my alertness, so I like to have it.
What
will take a serious hit is Vaping As A Hobby if the Deeming Rule gets enforced. New hardware will dry up. Packaged coils will become a problem . But, if you can build your own: An RTA/RDA can last forever. Coils can last a long time and a little wire can go a long way. So can cotton. A quality mod can last a long time, too. My over-three-year-old eVic-VTC Mini is still going strong. (Though, admittedly, it saw no use in the intervening three years.) A well-made mech mod, taken care of, should last
literally forever.
Depression, for most people, is a state of mind. Shake it off
