Have you tried vitamin pills? Not the kind you can buy in supermarket or chemist but more expensive and better quality ones you can buy on the internet. I recommend a site called Nutriglow, they offer vitamins at discounted prices. They say that you should get all vitamins you need from a well balanced diet but I do not believe this is the case any longer with so many foods being manufactured under commercial pressure! A lot of research has gone into vitamins and the quality has improved. I know it is going to be expensive but it is your health that is at stake. Experiment with different types, try one for a month and if it does not make a difference, try something else. I take Vitamin B complex, Vitamin D3 (5000iu), Magnesium and Calcium together plus Vitamin K2 (Professor Harrison says it is OK to take K2 with an MPN), Iron with Vitamin C, Gingko Bilopa. The Hydroxycarbamide made my haemoglobin drop so I am taking the iron. Some of these have made me feel a lot
better already. Also healthy eating of course, very little sugar and caffeine, no dairy products. Good quality foods, organic. Lots of fruit and veg, some meat. You need to experiment because we are all different.
