Don't overlook Omega 3 in large quantities. The clinical trials that
I've read about that were successful used a minimum of 6000 mg of Omega 3 from
fish oil. Here's testimonials, both good and bad, about Omega 3 and
bipolar.
Also look into meditation for healing bipolar. Here is a site about a
woman who cured bipolar and loads of other mental issues with meditation - and a
healthy diet.
What I've found in relation to both anti-psychotic medications and cannabis
is that they open up your energy system - particularly your chakras, allowing
unwanted and debilitating energies into your system.
