Thx Bex, Sorry I wasn't clear. I have been taking DMSA for 3 mo's. 3 1/2 days on , 3 1/2 days off. A week a go I added the ALA also and am taking it the same time I take my DMSA, every 3-4 hrs. My questions is when my 3 1/2 days of DMSA has ended and I take a 3 1/2 day break from DMSA do I still take the ALA? Or do I only take the ALA on my On DMSA days? Sorry I wasn't more clear. Thx for the help. Diane
