I have a wonderful friend who has both these issues. She actually has done over 20 LF's and then became quite ill. She was diagnosed with Hep C and a very high count. shortly afterwards her thyroid has gone haywire and she is having great difficulties. She has a large nodule on the thyroid and CT scan has shown something on her liver. She has not had a biopsy done on it and not sure she is going to. She is thinking about starting the LF's again but is a little concerned with all that is going on. Her biggest fear is the effects of a Liver-Flush on her thyroid.When the thyroid really acts up she can barely function. She has been to numerous doc's, alternative and conventional and hasn't gotten much help. She is hoping someone who has these issues or knowledge can give her some advice. She does not have a computer so I'm writing on her behalf. Thanks so much!
