Thanks Zaini, Andy, Nice friend, Narendra, Manal, Sf,
 thanks for the replies and suggestions, 
 I think the name of the chelating drug which I used previously was desferoximine,
 the haematologist has suggested another one I am not sure but will find out.
I do drink a lot of tea. not green tea but regular tea with milk so I guess thats helpful too,
thanks a lot again for welcoming me and giving your suggestions, I ll keep posting, God Bless you all.
