I never found a way to deal with anxiety and insomnia without medication. I tried ayurvedic, homeopathic, acupuncture and herbs. Both of my parents had the same problems so I guess I was just hardwired this way.
Everyone is different, though so maybe these other ways will work for you. I'm especially sad about the nausea. I take alprax when I get out of control even though I know it's not very good for me. But the anxiety is worse for me.
I hope you feel better soon.
