Yeah I've been doing this for the past week. It came to me one morning while I was preparing my usually green tea. Now I take a whole lemon to work with me each morning
The bottle on the desk trick doesn't work for me. There are days I'm so run off my feet, I'm hardly at my desk and other days I just procrastinate the day away, in which case I usually make several trips to the staff room to make tea, chat with colleagues.
