1) Go to vrp.com and buy 12 bottles of 25mg DMSA capsules (12 bottles = quantity discount).
2) Start with one capsule every 4 hours, 4-7 days on and 7 days off and see how you feel. Slowly dial the dose up and/or shorten the time between doses as the symptoms become more tolerable. (I am currently at 50mg every 2 hours)
3) After 3 months of DMSA, add alpha-lipoic acid, starting with 25mg every 3 hours (or a lower dosage if you can find lower dosage capsules). As with the DMSA, slowly dial up the dosage as you can stand it (I am currently on 25mg every 2 hours, taken together with the DMSA).
You should also load up on vitamin C, 10g/day or more, as it is crucial to keep your glutathione levels up as you detoxify.
Those have been the basics for me (based on Andy Cutler protocol).
