Girls, I need advice. For those who are sick with or have recovered from a cold, ARVI, or the flu: a pinch of baking soda, lemon and boiled water. Is it okay to drink such a solution? I’ve already had 3–4 cups over the whole day and only now I’m wondering if it’s harmful?? I sweat a lot and my nose cleared up, but after a while the weakness and nasal congestion come back. I have to take a COVID test in a few days for the maternity hospital — I’m afraid it might come back positive; acquaintances had ARVI, but when they got tested their tests showed COVID ? Strange as it may be.
