anybody know how to not lose weight on this shit lol, MULTIPLE QUESTIONS, NEED BEST ADVICE/ANSWERS PLEASE

title says it all, im skinny af already (around 145 or something like that) and i just barely started smoking like 2 or 3 weeks ago (cant exactly remember cause i've been on a big ass "drug binge" lol [shoutout xxxtentacion]) as you can probably tell, i've been up for a day and high af rn....

anyway, i wasabout 145, and feel like a already lost 10-15 pounds (i barely eat on it, maybe that's the problem, and no sleep) but anybody know what types of foods i should eat, i heard to make absolutely sure you have great hygieneor else you'll look like shit, but basically i have to force myself to eateven just snacks, cause i feel like i'm going to vomit, once i get that feeling i take a break from eating for a few minutes (side question: am i just tripping or would i actually vomit if i kept eating) i also smoke hella cigarettes when i smoke, which i switched to vape yesterday, cause i know that gets rid of appetite very easily. and before you guys get all judgemental, i went on a drug binge, then quit for a week, now yesterday/today is my 2nd binge cause i work and i have the weekend off (yes, i know, a functional tweaker, very un common lmao {im joking})

back to the subject tho, should i eat more than normal, or am i going to lose weight regardless? if i am, im definitely quiting, cause im either trying to stay at around 150, or gain more weight.. and i got to much to lose if its going to make me look like a obvious tweaker eventually (i feel like tweaker is such a negative word, but oh well.... it is what it is, i do meth)

thanks to anyone that has experienced this issue or knows about it enough to give me advice (also, im trying to control when i smoke it, like im gonna smoke maybe once or twice every 2 weeks, maybe a lil less sometimes, maybe a lil more.... is that even possible or does the urge become to strong?) thanks again for any helpful answers... please, no bullshit, i get enoigh bullshit from the tweakers in my area (they're the type of tweakers that make meth look super bad, you know what i mean, homeless, asking for change, stealing, etc....)

i also know a few cool meth users tho, that dont like to do any of that and are as honest as your gonna get when dealing with this sort of crowd (im not judging anyone, some of my close friends do all that negative stuff, but they're still cool people, i just wouldnt trust them with much
