I am finally seeing sense and taking note of those who told me it was fool hardy to self treat.  Like my IC I'm as stubborn as a mule but the games up, no more self prescribing for me!  I stupidly thought that the rash on my arm was from die off but have had it confirmed as vitiligo.  It's been growing in size since starting the supplements and it's quite clear that there is no pigment in the area on the inside of my arm which is now 4x3 inches.  if this had been my face I'd be very mad.  Again I don't want to scare any newbies, I would say do the diet until you can get further help or just get further help.  Don't try winging this thing on your own - I fear I may have altered my blood cells with my blind supplementing.  I've learned a lesson at least.  I've not checked but I think this could be permanent and as always if anyone has any info please throw me a line :)
