Interesting about the teeth grinding thing - I have been a horrible teeth grinder for about 20 years now and as time has gone on it has created many symptoms for me - headaches of course, nausea, brain fog and TMJ problems. It is probably the main reason I found out about mercury because I went to a holisitic doc to try and get help for the daily headaches and he tested me. So I got amalgams out last month and have gone to the sauna almost every day and no nausea, no jaw pain and only mild headaches more of a detox than from grinding. Last week I missed about 4 days in a row due to starting school ( I am a teacher) and by the 3rd day I felt all of the symptoms come back. I know I am grinding more and I have had horrible nausea and headaches the past several days. I am back to the suana but it may take several days to decrease the mercury load. I haven't started chelating yet because I am doing a parasite cleanse and wanted to wait until the 3rd month after removal. Today I feel very detoxy - tired, nausea, joints hurt, headache - time to rest.
