I also get that "oh my goodness, she's coughing up her toenails" cough. The one where I'm in Target and I start coughing so bad that I start crying. Here's what I do... I keep Halls cough drops with me at ALL times. If I start to get a tiny tickle, in goes a cough drop. I mean I have a bag in my desk, a bag in my work tote, a bag in the jeep, and I keep a handful in my purse (yes, even in the summer).
But...all bets are off at night. When it's really bad, I can't lie down (drainage, etc starts another round of horrendous hacking coughing)...so the choice is keep hubby away w/coughing (as well as myself) or try to sleep while sitting upright. Neither works...so thank goodness my doctor will prescribe Robitussin w/codeine. I recently ran out (on a Friday night)...on-call doctors won't do controlled substance refills over the weekend, so it was Monday before I could get in touch with my doctor. I think it was a combiniation of being so exhausted from lack of sleep and being so sore from coughing that prolonged my recovery. YUK. I'd ask your doctor about cough syrup w/codeine!
Good luck and I hope your cough goes away!
