That's more-or-less in line with my personal experience. I usually drink tea, because I like a hot beverage, but find that my quality of sleep and overall sense of wellbeing tends to suffer if I drink coffee. Even when I only drink it in the mornings. But I do still like (don't love, but like) coffee, and most cafes and restaurants in my part of the world can't make a decent cup of tea to save their lives, so I often just drink coffee when I'm traveling. And I find that, even after only a few days of drinking coffee, I will experience 2 or 3 days of cravings once I get back home and return to my regularly scheduled pot of dragonwell.
