I think if I was in your shoes, I would try 12.5mg ALA/25mg DMSA every 3 hours. Find 50mg ALA capsules, and divide them in 4 whatever way you feel most comfortable. An easy way would be dissolve one capsule in a certain amount of water, add some vitamin c, and drink 1/4 of the solution every 3 hours. Don't put DMSA in water, its not as stable.
