Well that's one more done! Although I had some coffee before heading to the appointment I still didn't breathe in quite enough. I found that I could tell when the machine was about to stop and I'd breathe in a little more deeply before they asked me to. They said they noticed me doing that and that they thought I was very smart for figuring this out.
When I got home I did some research on this holding my breath technique and it turns out that it has a name: Deep Inspiration Breath Hold (DIBH). Who knew? There's even been a review study about it saying that it is effective. That's good!
One thing my research discovered is that some treatment centers have ways of giving visual feedback so that the patient is better able to tell when they're doing it right. The best way of doing feedback hasn't been decided. Neither has the best instruction set. But they're getting there - this is a new technique, developed in the last six or seven years, and so of course it won't be perfect. I'm just thrilled that I get to do something new.
Side effect-wise, I'm doing ok. I'm a little tired and sleeping deeply at night, but I was also up before 7am. My sternum is sensitive and hurts occasionally (especially when Gozer steps on it!). I did the manual lymphatic massage exercises yesterday and they're definitely making a difference - my hand is smaller and my sweat and other excretions smell funny. At least the toxins are leaving me :)
