Ferrous sulfate
"After being terrified of blood tests for years, I finally had one after my fainting got worse and I thought it'd be smart to check it out, I always knew it'd be lack of iron because I'm not a fan of the foods that contain iron. I've been taking the ferrous sulphate for nearly 2 months now and although I feel so much more energetic and no longer get tired at the top of the stairs or faint, I often get awful stomach cramps of which I expect is due to the constipation but I can only describe them as being a whole lot worse then period pains and also a huge lack in appetite. I'm already underweight and I worry I'll get further complications due to not eating other types of food, but all in all the pill have made me feel so much more energised"
