I was exercise intolerante before amalgam removal , I would do a light work out and feel like crap within a few hours and on somes day part of the next day too, I had some symtoms after amalgam removal but not as bad ,It started getting better as I started to heal ,what really helped me alot was doing colinics one every week for the fist two months ,this will help you get those stubborn toxins out and help you heal much faster
