I would never ingest raw baking soda. That’s asking for problems. With the very small amounts I use diluted with lots of water, it’s not a problem considering how low my blood pH is.
I have recently started drinking EVAMOR bottled water. Has a natural pH of 8.8 - 9.2. I drink it for about 1/3 of my fluid intake and seem to have more energy because it hydrates faster than lower pH drinking water. I also contains some other minerals that may help.
I’ve stopped drinking sodas for the past three months and drink the Higher pH water instead. It’s a lot more refreshing.
I began writing a chapter on “drinking water” and it became a 3rd book.
Keep doing what you’re doing and avoid all municipal tap water.
You’re on-target, but keep eliminating the toxins; soda is but one of many.
