It's a lack of bileflow, with the strep C being likely at the root.
I found ox bile capsules helpful in this condition just this week.
Restraining from food can give your body a chance to fight the virus with ease. Much of the energy for digestion is diverted right now against the virus.
Stay hydrated, get your salts and herbal intake high.
Strong chamomile (just add extra tea packets to the water, or break open the tea packet to eat the contents),
Lavender flower (again, eating the plant is most powerful),
Green tea, especially bitter matcha where you drink the powder-
All those can help.
Ask at the chemist's / pharmacy for activated charcoal capsules/tablets and use plenty of them interspersed throughout the day, that will help alleviate the feveraches too.
Right now the liverflush will initiate the digestive processes again. Your body is giving you the right messages with lack of appetite.
If you're using olive oil with a very bitter flavor, oil pulling with it will get the essential oils (the bitters) from it, into your lymph system- very good for fighting the infection. :)
