From the beginning of 1907, Sibelius again indulged in excessive wining and dining in Helsinki, spending exorbitant amounts on champagne and lobster. His lifestyle had a disastrous effect on the health of Aino who was driven to retire to a sanatorium, suffering from exhaustion. While she was away, Sibelius resolved to give up drinking, concentrating instead on composing his Third Symphony. He completed the work for a performance in Helsinki on 25 September. Although its more classical approach surprised the audience, Flodin commented that it was "internally new and revolutionary".
