Best I can do is give you the benefit of my experience. Muscinex, would be pseudoephedrine, like the so caled 'muscle relaxer, i received a couple months back from, ironically, the ER. I was in for chest pain. Well, it turned out the chest pain was costochondritis, common, but the ephedrine compound nearly killed me. I am on two serotonin boosters, one being elavil. You should be titrated up from a low dose, it will help you sleep, but avoid OTC cold and decongestant medicines.
