So. Sick. OMG 😩

I started getting a cold a few days ago and it is so bad. But only at night and super early in the morning! I cannot stop coughing. I've been taking Tylenol cold & flu severe and it literally doesn't do anything. I just wish I could take NyQuil 😭 I have cough drops, Vicks, been taking vitamin c, drinking tea!!! NOTHING is helping. I can't sleep at night and when I finally do sleep it's quickly interrupted by a coughing fit. Does anyone have ANY advice on what to do or what helps?!
