I find my sense of smell and taste is a lot sharper than it was, and I can smell food and drink a lot more than I used to, for example its someone birthday in the office so they put a load of pasties in the kitchen, and even though my office is over the other side of the building I smelt them long before I got the e-mail!
When I went into the kitchen for some water, I could smell them even more powerfully, and surprisingly (as I love pasties), whilst I enjoyed the smell, the thought of eating one didn't thrill me, in fact it turned my stomach a bit.
