Hi everyone. I'm new to this board so please forgive me if this poll already exists. I'm not trying to pick a fight or anything like that. I just want some honest answers. It seems as if I've been researching my own personal issues for a very long time now. My main compliant is the bran fog that I have been experiencing for a long time (possible for more that 15 years). I know it's not normal since every now and then I snap out of it and I can think clear (like the fog has lifted). But most often I struggle to get the clear thinking I'm aiming for. This goes hand and hand with the fatigue I feel and the upper back pain that I can't shake. I've visited the other avenues of possible heath concerns but seem to reach a dead end there. I saw the smoking teeth video but am having a hard time believing it since mercury vapor is heavy and should flow downward. So I'm trying to believe that my problem is truly Hg toxicity and not something else. This one is a bugger to figure out. I have 7 or so fillings and 2 of which are very large. I would get them removed if you guys are actually experiencing some benefits. Please, Please reply even if you don't think it's not pertinent, etc...
