After three sleepless nights, two of which were spent in the guest room so I wouldn't wake Dave with my coughing, I decided to go to the doctor today. The verdict: a sinus infection. Lovely. So I have drugs for that and drugs to relieve my cough. The latter will likely knock me out, so I took 1 instead of 2 tsps. and hopefully I will be alert by my 4pm student today. Goodnight!
