Peace! So flouride is no good (stop drinking any tap water, get fluoride free toothpaste & aluminum free deodorant). Avoid alcohol, caffeine, and as much sugar as possible. The things I've tried that have really worked to activate it are Haritaki capsules, MSM + acerola powder, & skate liver oil capsules (not vegan). I followed a lot of the advice on this website

Lastly, if you're interested in doing dreamwork there are herbs that are good for that as well. I order from Resonance (if they're in stock) or Anima Mundi.
