About a month ago, I cut down from drinking two (sometimes three) cups of coffee a day to just one. This has been a tremendous change for me. I really savor my cup of coffee in the morning now. And if I make a whole pot out of habit, I can just put it in the fridge and not have to worry about making coffee the next day. I don't get coffee crashes anymore. I feel better throughout the day, and have noticed that overall I am less grumpy (unless I got zero sleep... then give me all the coffee you have). This switch to one cup a day has made me grateful for coffee even more than I already am.
