I have been having bouts of heartburn and sickness which appeared regardless of what i ate. I sort of linked them to iron tabs but everyone was saying that it was probably just a coincidence. Then i started to notice that when i was also constipated (expected with the iron tabs) and that the heartburn and sickness occured at those time. As soon as i managed to got for a poo it cleared up. Anyone else found the same or is it just me imagaining it ?
