But boredom? Total trigger. It's not like I actually wanted to smoke - but there was nothing to really do instead. I couldn't read because my head hurt. I couldn't stare at a screen for too long because my head hurt. I couldn't listen to music because my head hurt.
So I thought about smoking. A lot.
Back when I was a smoker, if I had half a day on my own and nothing to do, I'd put in some quality chain-smoking time.
Bored? Light up. Bored again? Light up. Repeat ad nauseam.
But I wasn't about to rip my patch off and drag myself down to the dairy. Instead, I spent a tiresome day trying to sleep, staring at my watch, and pondering how I ever got myself into this mess in the first place.
Hopefully I'll feel better soon. Because, thanks to the tedium, this was probably the worst day yet.
