hey tlin...
i'm the wabbitte for whom andreas left that message that hanna forwarded to you :p (pink eye persistent coughing etc. after Amalgam removal)....
i'm pretty convinced at this stage that along with my diet, it's my still persistent acid reflux that's causign the coughing... i think Liver Flushing until all the stones are gone will definitely help me -- i've done 4 successful Liver Flushes thus far and plan to do my 5th at the end of the month.
if your dad has acid reflux and dry coughing, i have a feeling that Liver Flushing will also help him overall, along with eating for his body type. there's tons of info on how to do Liver Flushing right here on CZ... i also got Andreas Moritz 's book "the amazing liver cleanse" i think it's called -- he has a new edition out i believe -- i found the book enormously useful in giving me why's and wherefore's of liver flushing
hope this helps,
wabbitte
