So I have roughly 250mg of pure dxm, but I want to take 300mg. So I also want to take 2 Coriciden cough and cold pills with 30mg DXM and 4mg chlorpheniramine in each. So it's going to be a total of 310mg dxm plus 8mg chlorpheniramine. How is this going to effect me? I heard people can die from taking triple c's but I won't be taking that much.
