"..."old ski boot" or consider a leather hiking boot". Gosh, I'm thinking that is not for me, lol.
Many years ago, a coworker got me hooked on Green Mountain Caramel Vanilla Cream coffee, a light roast coffee. I add 2% milk, no sweetener. Did you know light roast coffee has more caffeine than darker roast? Counter-intuitive for most people, who seem to associate dark, bitter, strong coffee as having more caffeine.
Caffeine doesn't keep me awake at all; sometimes, I wish it would! If I don't drink coffee, though, I do get a caffeine headache, so know I am addicted to it. Due to stomach problems and Barrett's esophagus, I shouldn't drink it, so limit to one cup, max, per day. Sometimes only half a cup - and yes, with the price now, I do put the other haff in the refrigerator and warm it up the next morning. Silly, maybe, as it's about $.50 per cup, but dumping it seems so wasteful. Hey, we all have quirks.
I used to love tea, but it actually bothers my stomach more than coffee now, so rarely drink it. When I do, it's Harney and Sons Cinnamon Sunset with nothing added. Much as I love sweets (baked goods), I detest sweet beverages.
Now that the weather is so flipping cold (9° here this morning), I will actually heat water and drink it. Water is, by far, my beverage of choice. How dull!
