With detox often there is a worsening of symptoms. When I am chelating with ALA and DMSA I usually get a mild headache.

Imo chelation with ALA and SMSA together is what is crucial to detoxification. Also important though is getting plenty of fiber and not being constipated. Becoming constipated during chelation can make you feel extremely horrible. To help prevent constipation and to stimulate the adrenals, I use licorice root.
The tea is delicious.
