Hi there. I haven't been vegetarian for years no. I used to eat fish last year and bone broth / vegie soups a fair bit. At least 2 or 3 large pots a week last year (when I could actually tolerate much more normal solid food without the horrendous effects I get now). I'd use organic chicken drumsticks in large soups with organic veg etc. Was also organic juicing at the time. Definitely cannot say I havent been doing the right things for years! Probably the 'worst' thing I was eating was rice crackers with hommus or other non dairy dips, which really isn't that bad at all.
I should certainly get the hair analysis though, have wanted to for some time. I know I have mercury issues (one large dental Amalgam has been ground down to almost nothing by night time teeth grinding over the last few years). I cannot tolerate though, any chelation! Except chlorella, that doesn't seem to hurt at all, but also doesn't help much.
