6 years ago I started developing hypoglycemia type symptoms; ie if I eat simple sugars I get really bad headaches.

I read this was a symptom of mercury poisoning;
I had pretty much phased out drinking soda myself (only had it on the rare occasion) but after the headaches I stopped altogether; had to cut down on the fermented grape stuff too <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
