We probably got Ba5. It left us dizzy, low energy (likely dehydrated and hypoglycemic, so we took carbs and water) after fever and aches cleared, with anosmia. It took a couple of days to get to 90% and we were at 95% after a week.

We used a naturopathic/allopathic approach--elderberry concentrate and calcifediol and zinc. Fever/aches cleared after 48 hours. No rebound, but lots of sinus drainage. All have comorbidities except the child.
