Just as the title says.

I’m very anemic, and I’ve been struggling to address this. In the last week, I started taking iron supplements to address my fatigue, and things feel a bit… strange.

I’m still tired, but I sometimes feel/am acutely aware of my heart beating?

Idk. Shouldn’t take only a week to see/feel results, right?

Any insight?
