excessive burping, vomiting, feel hungry but dont want to eat

Over the past week I've woken up with massive amounts of mucus in my sinuses and it feels like some in my esophagus or windpipe last Friday and Saturday I puked probably 15-20 times and sometimes its just mucus and bile but sometimes its a bit of food too, my mucus also sometimes has black (or brown i cant tell) spots in the mucus.. Ive smoked alot of pot and thoight this is juat tar? I felt dizzy and lightheaded and nauseous.. The puking happens Especially in the morning or when i eat anything except jello or fruit it makes me feel like puking and it feels like I have gas trapped in my system as I burp pretty often but it feels like something needs to come out or something :/ at times I feel hungry but don't feel like eating but force myself to eat and sometimes i feel really hungry but it goes away fast and when i eat its sort of hard to swallow the last bits of a bite, not for my throat but more like a lack of saliva makes it hard to go down. I feel like I have my normal amount of energy but I haven't done too much the past week.. Haven't been pooping much maybe a tiny one a day or once every two days and its diahrreah if I do, although I pee a normal amount. I was twitchy and shaky but I went and got anxiety meds which have helped solve the twitchy and shakiness.. This is all I can think of ATM.. Any help would be awesome I went to the hospital but get results tuesday. Thanks in advance for anybody who replies :)
