I agree, it is a test of indurance. The round I did this week was a slight departure from what I have been doing for the past 4 months. I decided to experiment with a hypbrid protocol. Instead of my usual dose of 100mm of ALA, I did 50mm and mixed it with about 1/2 dropper of Cilantro from source naturals along with the 100mg of DMSA every three hours.. It seems to have gone o.k.
