Very hard to say. Also: IANAD. “Morning breath” can result from a variety of causes, such as dry mouth because of sleeping with one’s mouth open or poor dental hygiene (bit.ly/sleep-bad-breath). Interrupted sleep cycles or poor sleep quality can result in bowel problems (bit.ly/sleep-ibs). If you’re planning on mentioning this, be kind. Perhaps tell her you’ve noticed your own odor & your plans for reducing it.
