I worked in a wonderful, funky old coffee house for 15 years, so I have a lot of experience with espresso, coffee, tea and all sorts of drinks. I used to work the espresso machine - made beautiful lattes, cappuccinos, etc. I miss working there.
This winter I've been drinking a lot of hot chocolate (Ghiradelli). Sometimes I put a peppermint tea bag into the hot chocolate, gently stir it around...wonderful peppermint hot chocolate.
I love espresso and can't stand chain-stores espresso. It's garbage. Only indie coffee houses/cafes have real espresso. Some years ago I was in Paris and was surprised that their espresso was no better than the espresso I made at work.
One of the most "useful" drinks that I came up with was a mug of hot herbal tea with 2 cough drops melted into it. Great if you have a sore throat or cough!
Some mornings I make weak mochas for myself (brewed coffee, chocolate, milk). I wish I could afford a home espresso machine!
