Three times now, in the last two weeks, I have laid down to bed at night, only to experience (for the first time ever) heartburn so painful that it drove me out of bed, dressed again, and to the store at midnight to get OTC medicine.
This morning, after ingesting my usual double-strength french press of coffee before work (and god it was delicious; I make a truly excellent pot of coffee), I realized that this might be the problem.
So, for one week, beginning tomorrow, I am giving up coffee. As an experiment. As a substitute, I plan to drink green or herbal tea. And probably kill people.
Consider this your warning.
