I puked every time on syrup but never with coriciden however avoid coriciden cough and cold the antihistamine in it can kill you at a sizable dose. Stick to pure dxm no alcohol or active ingredients. Lastly tylenol(acenomenophen) is okay with dxm and won’t normally make you puke but the maximum daily dose for healthy adults is around 4000 mg and still that’s much too high to use in recreational dxm use . Stick to tablets or liquid with only dxm and no other active ingredients or alcohol including Tylenol. Get your liver tested too as recreational dxm can be harmful to the liver especially with multiple uses
