Hi, im asking this question for my boyfriend, for the past few weeks my boyfriend has been feeling very nautious, he has lost his apetite and thirst, he cant sleep, an keeps spitting out cups full of white clear bubbly foam and sometimes there is a yellowing in the foam. He says its worst when he lays down and he is loosing strenght and energy and has mood swings and chills. After being forced to eat he feels like throwing up. He has a lost a few pounds and he has headaches. Is there any thing you coul tell me in order to help him or something you recomend for him?
