Absolutely - referring to positive thoughts. That is one think I have noticed since I got my amalgams out - I have a better outlook on my situation. It's just a mental clarity that I never had. I have done a lot of different therapies - more mainstream than alternative all of which never helped so after awhile I got sort of pessimistic about a new therapy. But this (meaning cleansing and chelation and detoxing) I know is going to help me dramatically - over time. I keep telling myself "you didn't get this toxic overnight so it will take some time" but everything helps. I have been doing the castor oil packs too - not overnight though. I should try that - do you use a heating pad? I usually use a rice bag in the microwave but it doesn't stay hot for that long. I have to keep heating it up.
