I am a fan of homeopathic alternatives and take
Ferrum Metallicum 30X, HPUS daily, Folate and drink WATER, NOTHING ELSE.

Sutimlimab. i did some research about this medication and is really strong and effective but it doesn't lasts forever. at one point you will need to do an infusion again. is also called Enjaymo and is a dedicated med for CAD.
can you say more about the side effects? i was kind of interested in this because is more effective but the side effects were kinda off putting for me and i and a bit scared to try this.
maybe u got a bigger dose then u needed or was really concentrated. but it must be really potent and effective as a medication i guess if your HG levels were spiked up so high.

you could add a iron tablet to keep your HG levels stable. it helps to create more red blood cells given that some of them are getting destroyed. also i take folic acid every day.
