How can you see suffering in the breath?

In his book Breath by Breath , Larry Rosenberg says that being mindful of the breath, as in the Anapanasati Sutta , is a complete practice and can lead to complete liberation. Following on from that I would think it should be possible to experience all three marks of existence in the breath. From my own practice I can feel both the impermanence and no-self aspects of the breath. They seem fairly evident even with access or just momentary levels of concentration. However I don't see the other mark of conditioned existence i.e. suffering. How can one see suffering in the breath? How does this come about? Are there any traditional or contemporary writings on the subject? Many thanks for any all help
