Good evening I have low hemoglobin, more precisely it dropped sharply from 140 to almost 85 I've been taking iron and a bunch of medications Now I noticed that after I take an iron tablet, I immediately feel bad, nausea and so on The doctor asked...result: shrugged and said continue taking them Honestly, I'm tired of feeling like I'm hugging the toilet I won't drink any more tablets Who knows, please advise I don't have the strength... I want to sleep at least for all the pregnancy, 30 weeks of toxemia, nothing to eat or do
