I did not have symptoms like that, but I think that no matter what you do there is going to be additional exposure during removal.
What I did was wait until I was walking into the dentist office and take a ton of activated charcoal right then. Then immediately after removal I started taking massive amounts of vitamin C for the next 3 days and made sure I was having multiple bowel movements each day.
I know a lot of people report getting vitamin C IVs after removal, I imagine that would help too.
Makes you feel good you are getting them out though, doesn't it?
