Hello I have low iron and vitamin d, Gilbert'Scott syndrome, anf Severn ibs (to the point where I am on lower than the fodamp diet and I still have symptoms alot) and I have my vit d sorted finally but the iron tablets the dr gave me (ferrous sulphate 200mg ) have made me so ill. I'm supposed to be on 3 a day (ferratin is at 4 but the one i always go by is the old standard pregnancy one whoch is at 10.4) but i started on one because I was worried and they have wiped me out!! I had bad stomach pains, nausea, cramps, I felt like I had been hit by a bus, i was and still am exhausted and breathless. Has anyone else had this or is this just me?? BTW I stopped taking them 2 yesterday and still feel like it. Help??
