Hey , I 've been out cold for a week , today I printed a cough medecine with bromhexine combined with ephedrine , it has now gone 5 hours ago I took medecinen 15 ml and I was experiencing stomach pains , vomiting , tremors , very fast heart beat , chest tightness , and confused what should I do? I drink a lot of water but I vomit it up even hot water but the same result. I dont now what I should do? I Thinks some of this can be side effects of the medicin but I really do have a horryfing stomachpain in the right side. Thanks!
