Ever since COVID came, we have had the nasties viruses and full blown COVID nearly every winter (and some in between). Everytime my daughter brings a bug home , it just absolutely decimates us. Prior to COVID this never happened. I am tired of being sick. So sick I can't get out of bed everytime this happens. Absolute exhausted. Anyone got any help or tips? Is there something we are not doing or any particular supplement etc that can help? At a loss. Thanks
