Cycled to the clinic on me Brompton. Nurse was surprised to get a CO reading as now nearing 48hrs quitting. She suggested maybe I should go buy a CO detector. I said maybe it's traffic fumes. Nah, she said, unlikely, check yer boiler. My partner still smokes.... which is tricky. Wasn't too bad at work today, though a couple of stress points had me fidgeting mightily. Popped some mints. It's tough.
