It is nasty. It was by chance that I started feeding John cranberry everything. It was fall and fresh cranberries were in season. I made him cranberry tarts and chutney, preserves, etc...
Not that you would want to take another pill but they do have cranberry capsules. You can also look into D-Mannose. It's the substance in cranberries responsible for the effectiveness of cranberries on bladder infections. It's a powder that you can mix in water or juice. It a simple sugar that doesn't mess with your blood sugar.
Here's an article on a clinical trial where they used D-mannose for UTI's and speaks to how it works. Of course this is not what you're dealing with but will give you insight to the safety of D-mannos/cranberries. I'm sure there never was and will never be trail on this for the BK virus.

Blueberries can also be helpful.
Glad your white count is up there. Hope you see relief soon.
