Thanks for your help Bex!

I'm taking 12.5mg of DMSA along with 2mg of ALA. The symptoms gradually increase over a 24-48 hour period. I feel very fatigued, irritable, depressed, severe headache, and lower back pain. I'm starting to think my head must be loaded with mercury because when I had my fillings removed 22 years ago, I remember my dentist saying that whoever put my fillings in obviously didn't know what he was doing. Because according to him the percentage of mercury in my fillings was MUCH higher that it should have been.
