I'm nauseous all the time, when I wake up, before I eat, after I eat, when I'm falling asleep. It's probably about 7 hours a day I just don't feel well at all. Has been happening for a month or so, I'm rapidly losing my already small appetite and becoming even more underweight than I was. I eat kinda healthy and drink water every day but I don't excersize at all. I just don't know what's wrong with me??
