I just wanted to mention that breathing correctly helps tremendously as well. I'm sure most people here have been told to breath deeply before, but what does that actually mean?

I always thought it just meant slowly taking in more air in one breath than normal, and only when you feel you need to calm down or relax. Last night while pondering why every single breath I take seems to create tension and precipitates stress (leading to 24/7 chronic low level anxiety) it occurred to me that I've been a shallow chest breather all my life. This poor breathing affects me so much that one doctor thought I had a pheochromocytoma (adrenal tumor) because my resting heart rate varies so much between exhaling and inhaling. All the other doctors just wrote it off as anxiety or white coat syndrome.

In a nutshell, you basically want your diaphragm to do most of the work for breathing, so allow your stomach to move, and don't suck it in! Exhaling with the diaphragm is important too. I feel much better and I only slept a few hours last night when usually poor sleep makes me worse. The only downside to breathing differently is that you'll be more aware of your breathing until you adapt to it.

And with that I think this thread can die now unless anyone wants to reply.
