Great!

So those were your last two amalgams? It's not reccomended to start DMSA with amalgams still in, but you probably already knew that.

Steams saunas RULES!

But CAN give redistribution too as everything else.
I reccomend higher sauna doses rather than smaller, as high as you can take.
Because low doses loosens mercury and sweats out only little of that which have been loosened by the heat,
On the other hand.. higher doses loosens more, but also sweats out a higher percent of that which has been loosened..
But ofcourse, listen to your body and your head (dizzyness, etc) while doing sauna... You know when you had enough, etc.... safety etc...
Drysaunas has sometimes been, ineffective and one time bad for me.....
I don't like dry saunas no more... steam saunas on the other hand is great, so GO!
It helps a lot!
If there is still mercury in you bloodstream after such a short time... YES.
The sauna, will in my mind, saturate the blood in mercury to a point, and then get much of that out via the pores.... That is my explanation for why longer sauna sessions is better than small ones for me.... Short sessions gives more redistribution with me, while long sessions gets more out and gives less redistribution...
I'm beeing repetetive, but doesn't want to get misunderstood while underexplaining...

When it is best to use the sauna in regards to chemical chelation, i don't know...
But i can tell you (They say garlic isn't a chelator, but only a mobilizer, I don't quite agree, but...) Well.. i CAN tell you that i once recently eat raw garlic and took sauna the same day..... and the results where "catastrophic" for sime time afterwards... it was too much.... both the garlic and the sauna probably saturated the blood with too much mercury at the same time..... Don't know.. but i think it must be that way...
I'm better now..... but it took some time to recover...
Basicly what helps me is Steam saunas once every 14 days (safety to not burn out my mineral base and crash into fatigue), Asian toilet (Squatting) helps rid the colon and CURES constipation! which is a must during any detox, garlic.. well i have becomen more sensitive to that.. at least raw, so im now more careful with that, btw synthetic garlic pills can be dangerous in other people's experience here, real garlic is said to be safer, however i'm saying be careful with garlic, i use fresh red chilipeppers in most food, stay away from food aditives, drinks a lot of water, use honey in tea... etc.....

I have not started any synthetic chelator usage yet, i still have one filling left...
I started doing saunas as a light version of DMSA in my mind, a year ago... until i could get strong enough to continue more amalgam removals....
However.. Cutler is known to have said that saunas equals dmsa.... so....
Any.... a year ago just after two drillouts, i were are "cripple" crying for help...
Today.... after lots of sauna and going to the toilet Asian style.... i am functioning and am happy again.... But NOT fully where i want to be... yet...
However... Yes. Steam saunas are great... Glad you have access to one.

About the DMSA.... Someone else of the reg's has to answer that...

Good luck!

And great health and healing to you!

Cheers.
