The freedom to completely incapacitate me. My "cold" -- yes, I'm still sick -- is actually bronchitis, according to the doctor at the walk-in clinic down the street.
So, no writing. I've barely been able to think. It felt like I had a glue factory in my head, and the constant, violent coughing was, if possible, less fun than it sounds.
Thanks to sleep, antibiotics and prescription cold medication, I seem to be on the mend.
