I've enjoyed reading about your recipe experimentation. I totally get your very real concern about anemia. You'll definitely need to watch that like a hawk. I'm so happy you're doing something for YOU. It's about time!
Oh no! I'm sorry you have to go through that. If you search "reversal" here, some stories show up, but I don't believe any of them post regularly anymore. Best wishes for a successful surgery and speedy recovery.
