Sorry Ann, you are wrong. I have long haul Covid and I can attest it is real. I learned how to overcome it by taking supplements which mitigates most of the symptoms. For anyone who might have Long Haul Covid, here is what I take everyday. Zinc, B12, C and D3. It works for me.
I take those as well, but most of them come in my daily vitamin, as directed by my daughter. I take extra D3 as well.
