ice withdrawal, If I don't sleep enough I tend to hallucinate with my peripheral vision

I have occasionally been on and off using meth for around 6 months or so and started noticing a few issues regarding my health... ill explain with brief details but I need to know if what i'm going through is just temporary symptoms until i stop using and if my body is going through some sort of fazes's? Also (if any) some recommendations on overcoming these symptoms so I can focus on getting my organs healed asap. Ok so one of my main issues is MUCUS, everyday i wake up and can feel some built up in my throat, all throughout the day i have to be clearing out my throat because it just keeps accumulating, its vary pesky and bothers the hell out of me i cant ignore it, and on top of that its vary difficult to spit out because its so sticky. Its usually a milky green color, other times it comes out clear, and sometimes its even joined by some blood... which is strange because i hardly ever snort the stuff, I usually just smoke it so how is that? Another problem iv noticed is a slight pain in my chest like inside my lungs that's randomly being triggered and at times when i stretch or flex i get a sharp pain around my abs as well, also i get this random tingle pretty much anywhere on my body every so often whether i'm moving around or just sitting or laying, i even get it on my face at times... why is that? Also sometimes (not all the time) when i stand up after sitting for a good while ill feel light headed and its occasionally joined by some blurry vision lasting just a few seconds, another thing I cant explain to well is a feeling of chronic gas bubbles building up in my stomach, followed by digestive problems and even passing a bit more gas than usual even if i didn't eat anything all day... I also noticed that if i'm going hard for like a day or two straight ill start going through a withdrawal if i don't take another hit before like 7 hours, I found this out after going hard for a day with no sleep, i had to go to work and before i left to work I still made sure I toke one last hit, around 7 hours into work (i'm in fast food btw) I start feeling some nausea and fatigue, I ended up giving in and the whole night I was throwing up every few minutes, even just swallowing my own saliva would make me puke... Another thing i noticed is that if i keep going hard and get no sleep for almost two days, i start to sort of hallucinate through my peripheral vision every so often and it gets worse if i keep going hard with two full days of no sleep, but they're not extreme in any way, my mind just sort of plays tricks on me. Here's an example, lets say i'm walking down the street and i see some dude through the corner of my eye, and at the same time in my mind i'm thinking of something random like a hat i'm planning to wear when i get home, well in my peripheral vision (not doing so on purpose) ill see that guy that's walking by wearing the hat i was just thinking of , but when i turn to get a full look at the dude he isn't wearing that hat i just pictured him with a second ago... that's what i mean when i say "mind playing tricks on me" (just an example mind you) Those are some of the main things i'm dealing with, if you know a flaw as to why a certain symptom is occurring other than an obvious reason or know what i'm going through or even getting similar symptoms speak out! or maybe i can help out with some advise as well. Anyways iv been taking it easy now but every now n then i get that dang craving again which does me no good in the end but its becoming a dang habit, at the same time i'm not trying to go to any rehab center or anything like that because I know i'm not griped that bad... its a habit few in my life know about and i tend to keep it that way. Again please speak out if you have any advise you think might help, i'm not trying to rot to from the inside out just yet. (The rest is just some background info) I just tuned 19, I weigh around 145 pounds, my height is 6,2, my body type is slime, and i have a fast metabolism. I tried meth back when i was 15 but it didn't really catch my attention in those days, I started going hard on it around November of 2016
