I purchased a chocolate muffin for a colleague at work - it was one you pick out yourself so i touched it to put it into the bag - when i got back to work i was sitting at my desk and all i could smell was this muffin - i washed my hands and put hand cream on to no avail - then i found a small piece of the icing on my jacket - the smell was driving me insane.  i too have noticed my sense of smell for all things sweet - it is very overpowering.
