It's been one month so I thought I would post an update. I still use the inversion table every day. I'm up to 8 mins, 2 - 4 X per day, and will probably hover around there. I'm not yet at full vertical. I think I'm around 70 degrees, but plan to progress to full vertical over time.

Pros:
- Reduced back pain
- Reduced sub occipital pain
- Stretches most (all?) the muscles in the torso and neck
- Taller back
- More symmetrical spine
- When partially inverted, can be used for a deep pec minor stretch

Cons:
- Some dizziness on returning to upright, though this diminishes over time
- Can be a little rough on the ankles where the clasp is made to hold you up
- Another thing to do on top of the other things I do (although worth it)

Sometimes I still have a kink in my back even after being stretched out. For that, I have found it useful to then lay on this:

You can't see it from the photo, but there are two rows of support ridges that run along the side of the spine. These can dig into the muscle tissue and feel pretty good. You can also flip the unit so the tallest portion is under your t-spine. I use this as needed and often with a pillow.

Getting back to the inversion, if you try it, I have two recommendations:

1) Get a table that has built-in heat

2) Start slow, say 30 degrees for 1 minute, and build up from there. Use a timer.
