hi acw56, yoga is a great tool as is meditation, I tried a yoga class on a whim last year, (after my T encouraged me to find ways to cope with my mood swings) and loved it, I found it to help calm and center, and be a healthy tool along with therapy. Meditation is wonderful in that it helps focus the mind.

And way to go and adding in excersice and eating better, our lifestyle has just a big effect as the medience we take does, I have found excersising regurarly and eating healthier has helped stabalize my mood swings

Much peace to you
