I took my 3 year old son's prescription cough syrup this morning when I ran out of dayquil. About an hour after My heart was beating rapidly and my hands and legs were shaky. Then about 30 min after that started i went to the restroom and threw up. After vomiting I noticed that all around my eyes and on my eyelids I have tons of tiny red spots. It looks similar to bruising. Not sure if I should go to the hospital or not. I have eaten a little chicken soupd and am sipping on water. I am feeling a little better but the spots are not going away.
