Hi I'm sorry for delayed response I have not been feeling well lately. I never feel well, but have had a harder time than usual of late due to very long work hours. I don't remember what the iron infusions were I had to fight to get insurance to pay for them and now they will no longer cover them. I just take over the counter iron supplements and the hopes that that will help. I am vegetarian everyone just keeps telling me to eat meat, but that's not going to happen. I never had these issues prior to covid and I've been vegetarian since the 80s. I truly hope that you will be able to feel better.
