Tabula Rasa

Have a headache the size of Mount Kilimanjaro and I didn´t drink anything but water on New Year´s Eve.
Had the first cup of coffee for the last four days fifteen minutes ago (currently recalling a National Geographic article about coffee that said, if memory serves, that it takes about one hour for the caffeine to kick in).

Memo to my own metabolism:
"Pls allow the caffeine to kick in ASAP. Tks & Rgds".

...Otherwise I´m as prolific as a dead seal.
