Since taking adderall my bf hacks, coughs, scrocks, whatever you wanna call it, CONSTANTLY. It's gross and it actually seems to be unproductive. He will do it for five minutes straight, claiming it feels like something is stuck way back in his throat but he never actually splits anything out. Ten minutes later, he starts again. Sometimes a teeny chunk of white (I'm sorry this is so gross) will come of it but not anything the warrants hours of phlegmatic coughing. He's also a smoker and def smokes more when on adderall but I'm convinced it has to do with the dry mouth effect more than cigs bc he did not used to do this. It drive me absolutely insane as I find it repulsive to hear it constantly. Anyone know of this being a dude effect and if there is anything to help stop it??
