@dawn16 Every so often I run out of iron pills and go "eh, I'll be fine. I will pick up more eventually" and by the next week I am tired all of the time, taking afternoon naps, drinking black tea for caffeine (which exacerbates the problem), and, in general, being a grouchy tired lump.
Then, after a week or so of being a lump I remember that I haven't taken an iron pill in awhile and pick some up and return to being a functional person.
I hate being anemic, I thought I wouldn't be anemic anymore because my IUD stopped my periods but no, I just am anemic. And I surprise myself every time that I forget that I am anemic and don't medicate myself. Ugh.
