Sunshine, just my opinion. Increase the DMSA dose. 6 mg is fine for starting off, but you would want to increase this before adding ALA. Because ALA is much more powerful in chelation than DMSA. If you cannot handle more than 6 mg at this point, I don't know if you'd handle ALA either...

That's what I would experiment with first before taking things further. I would try the 8 mg and if you do ok, you might want to try 10 etc. I would aim at getting yourself up to about 25 mg personally or even up to 50 if you can at some point. Then add ALA later as you handle higher doses of DMSA.

It's up to you of course, but that's how I would do it. It's great that you seem to be improving and it gets scary when you don't want to leave that point and push things further in case you ruin where you're at. But I don't think going up to 8 mg is too much. You can always try it and see how you go and if it gets too much? Just stop the round and have a break.
