My train of thought

at approximately 7.23 this evening.

I feel sick. Did I take promethazine* this morning?
Ummm no, cos I'd run out of diet coke** so was going to take meds*** in the kitchen instead.
But then forgot.
Ok, so, no promethazine, that explains feeling sick.
Hang on, no meds this morning****!
It's 7.23pm***** and I haven't taken my morning meds yet. Argh******!
:-o

Key:
* promethazine - anti-emetic
** diet coke - on offer in the local shop
*** take meds - swallow chemical joy. or something
**** morning meds consist of 5 pills. every morning (note morning, not evening)
***** 7.23pm - evening (thus not morning)
****** Argh - self-explanatory.
