Hello. I wonder does anyone experience diarrhoea and/or feeling unwell whist taking hydroxycarbomide for myloproliferative disorder (MPN)?  I've felt very unwell with diarrhoea, feeling washed out and nauseous on a number of occasions over recent months. It seems to happen when I'm tired or stressed but not sure if this is related to my condition itself or my treatment. I take hydroxycarbomide every day for thrombocytopenia and polycythaemia vera. Many thanks. Linda
