SCAREY!!!!!!!!!! I was always concerned about the effects of ANYTHING extra besides ketosis on my body... I felt so paranoid about it ALL the time actually... have had too many lectures against it perhaps. I cant see how it could really be so dangerous to be into it though or wouldnt there be huge warnings and a million books being pulled from shelves of stores? ah yea... Even Atkins mentions ppl who did induction for years...I am sure it must be alright then. I am jsut a paranoid person sometimes.
