Yes, like the others said. I'd probably be lost without it lately!
They say you can have up to two cups of coffee a day. I still drink it! Usually just one but there have been days I've had a cup at home and then gotten a latte from Starbucks later in the day.
Yup. I have a 22 ounce coffee a few times a week. It's fine, just like mostly everything, in moderation.
