Non-medication treatments for anxiety?

I'm not sure if this is what you're looking for, but this is what I use.  http://www.bachflower.com/rescue-remedy-information/  

You can buy it over the counter at drug stores.   They also have a rescue sleep, which I find really good for those nights when I can't shut my brain off.   HTH, GG

I use a product called natural calm. It is a powdered magnesium drink. Helps me to wind down and sleep.

You might look into progressive muscle relaxation. There's a book about it, called Progressive Relaxation. I've read this one, but it's rather expensive and I never felt as if I needed to refer to it again after understanding the concepts, so you might want to see if your public library has it or can get it on interlibrary loan before you go to the expense of buying it. The same author also wrote a book called You Must Relax, which I haven't read, but I think is the same information written for a general audience. Progressive Relaxation is more technical. The basic idea is that tense muscles go hand in hand with tense emotions, and relaxing the muscles relieves the emotional tension too. Hope that helps.

outfield - I participated in a study right after chemo - it was a quantified study specifically for breast cancer patients employing Mindfulness Based Stress Reduction.  We submitted saliva (ick - a lot of saliva) and blood samples which were tested for cortisol.  Then we were taught several different types of meditation, did dome exercises concerning control and the lack thereof, were to practice daily and attended classes weekly.  We were tested again after six weeks to see if our cortisol levels dropped.  Much of the study materials were based on the teachings of Jon Kabat-Zinn.  The instructor endorsed the book Full Catastrophe Living.  Linked below are some CDs (we were given them as well) that might be helpful, as well as the study.

if you are ER+, you might want to avoid lavender, because it may have estrogenic effects. Unfortunately this link doesn't say whether it produces those effects by inhalation, or only when eaten or used on the skin. I wish there was more definite information about that, because I have used a lavender-scented spray on my pillow in the past when unable to sleep and I'd like to know if it's safe to use for that in the future.
