Is it possible for a medicine to make you feel even worse? Before I took Nyquil on Monday night I just had an awful cough and a headache which kept me up all night. So I thought I'd take Nyquil and get a good nights sleep! That didn't work so well. And it seems my cough is mostly gone, but I've not only now lost my voice but my ears are starting to hurt as well as my glands. This sucks. I can't feel like crap with the crazy weekend we've got coming up. My ears feel clogged. UGH! How do I have a cold when it's 80 degrees out?
