Dark moods & depression are definitely common detox symptoms. To help these symptoms you can do the pulse dosing, a salt load, ingest half a teaspoon of Natural with a glass or two of water. Continue after an hour if you still feel bad. For me one salt load did the trick most of the time. If you don't want to ingest more salt, you can get magnesium chloride, the chloride is basically what helps you get out more bromine faster.
Also increase Vitamin C to bowel tolerance spread several times through the day & drink more water (not fluoridated or chlorinated city water)
If your dark mood is caused by fluoride, try boosting your Boron. I am taking 9mg Boron daily to prevent Erectile Dysfunction so 9mg is not a problems for me.
As a last resort, you can drop back to a lower dosage for a while if your dark moods become a problem. Also consider jumping up to 100+mg. Others have posted that it took more than 100mg to get rid of the detox symptoms.
