Went on a trip a while back with a relative, here are some of the things that they belived/behaved like(sorry for the long text):Needless gossiping and thinking that other people's achivements threaten your credibility. Anger/apathy/being dismissive as default, snarky useless remarks, belittling other people any chance possible, trying to seem superior through "presenting intelectual", playing "the devil's advocate" just to look edgy and be unnerving, beliving propaganda over science, not apologising when needed, lacking self awareness and being selfish constantly, not going to therapy&health check ups, making poor spirited jokes about other people, not respecting people's space, touching them without permission,being disrespectful on purpose to other people(and to yourself), and the phobias(homophobic, biphobic, transphobic, xenophobic),misoginistic,misandrist, ableist, rascist,antisemitic,heavily nationalist attitude, thinking the world revolves only around you and that other people are just tools&objects, not cleaning after yourself, expecting other people to take care of things for/accompaning you as if they have an obligation, thinking violence settles things, refusing to pay people because "it's for exposure" and "they should do it for the experience/self fuffilment", loud music in public spaces(please use headphones), dismissing people's religious practice just because it isn't exactly how you would do it, pressing other people to live the life you want to but not living the life you want to live yourself, being needlessy pessimistic and cynical about the future(guilty), not being bewildered about earth and not wanting to learn or practice random things(who has time to be hateful when you see a beautiful leaf that has just sprouted?), lack of wanderlust.

The fact that I am more invested of the aftermath of this rather than current events says it all. Be safe OP
First of all, I was having a nice day until I read this. But alas, here's my two cents. Since you said you will be travelling, not eating will be a problem. Why? As other comments pointed out and as I went through this myself a few weeks ago(not intentionally, just financially dependent on irresponsible traumatised individuals who get to decide when/what/why I eat- I am working on it, don't worry), not eating for extended amounts of time gets you weird cramps and liquid poop. You don't want that, especially when you need to move. I don't know the environment you will be in, but aim to eat a bit those days, processed solid foods will do. Cheese, eggs, bread(bagels),plain pasta(ALREADY BOILED) if available. Avoid sugar in fairly large quantities(dehydrating), coffee(obvs), fruits, even vegetables. Your body will hate you for this, so when it's over please take it easy and eat&drink water properly. It's good that you will be moving, hopefully not too intense activity(because you'd need to eat/drink water properly) as that will distract your brain from wanting to eat/drink water.(again, sauce: former retail worker, wasn't done intentionally, I can't stress this enough. It just sorta happens). Make sure that you at least sleep and rest properly, and as others have pointed out, this isn't sustainable and not recommended by any means. Long term lack of nutrition fucks you up in ways I can't even begin to describe, take that shit from me. In the offchance you tattoo your asshole(and that you are one who has that tentacle tattooed on the asshole and are having it re done/touched up), you can simply wash after you poop, you don't have to go through this. Also you can try anti diuretic and anti liquid poop(for a lack of a better term) medicine. Looking foward for an update, hope you'll be ok.
