Smell of my breath improved after a series of 10 or more liver flushes.
It is definitively related, and the smell may be coming from your lungs or from anywhere between your lungs and your teeth.
Keep flushing. It is not an instant cure, as each flush improves slightly the health of your liver, which in turn improves the health of your intestines, which in turn improves the health of your whole body and in the end it improves the smell of your body, both inside and outside.
When it comes to diet, always listen to your body.
It will tell you what foods are compatible with you.
Keep flushing, at least one flush every month, or even 2.
