I'm not sure how you'd make bread with tonic water.
If you're looking for a way to make breat without yeast, one solution is to get some KEFIR.
Kefir is one of those things that has the great health benefits. It has bacteria and yeasts in it. It's has antiviral properties. Anti cancer properties.
The health food store might have the most natural kind. The supermarket might have Lifeway Kefir, which doesn't have the wide diversity of bacteria and yeasts, but it should work.
Here's some pubmed on Kefir and antiviral.
A novel kefir product (PFT) activates dendritic cells to induce CD4+T and CD8+T cell responses in vitro.

Lactobacilli have been widely studied for their probiotic effects and have been reported to function as antiviral and anticancer agents. However, the underlying mechanisms via immune modulation are poorly understood
