Oh good Bex that you are starting again. I feel like DMSA is already helping me. I had to get up at 2 am and 6 am though. Yea I think that ALA would be your best bet, since you've been in the game for a while already. You know I looked up 25 mg of ALA on some sites and I didn't like their products. They were cheap and had additives and flavorings. But I found out that a good way to make 25mg ALA out of a 100mg is to mix it in the water or juice and then just drink the 4th. I am thinking of ordering a 100mg of ALA from the site you suggested http://www.vivagen.net/detoxprods.htm
That's where I got my DMSA and quite pleased with their product and service.
