Sick...and tired

Ugh...I'm so sick and tired of being sick. I haven't slept good in a week. I actually don't feel too bad during the day but soon as it gets to be about 10 pm, I start coughing. And then I cough all night long. Makes it difficult to sleep for any appreciable length of time. I've tried taking Nyquil, cause that usually knocks me out, but it doesn't help. I'm about at the end of my rope here. I guess I could (gasp) go to the doctor. But that's SO not like me to do that. I avoid the doctor like the plague. It was really weird while I was pregnant to go there so often b/c I had avoided it as much as I could. But now...I need to sleep...I might just break down and go. I'm afraid though that they'll say there is nothing they can do for me. Now that would really stink...to pay my co-pay for them to tell me that there is nothing that can help me but some rest.
