I'm thinking I'm in the 3 characteristics but it happened not on the cushion and what happened wasn't quite what I expected. I try and note once per second throughout the day as a normal practice for me. I've also been practicing at looking at when things arise and vanish.
Recently I have been using the Pomodoro Technique for work and you basically time box your work with "X" for each 25 minutes and rest for 5 minutes and continue this throughout the work day. This is more for time management but I use mindful noting to note mental distractions as I get on with work. When I really get absorbed into work then the noting ceases until I feel I need it again.
One day I found my internal talk extremely IRRITATING and OPPRESIVE and I just said "SHUT UP!" in my mind and it quieted down and I just stayed in presence until the end of the day. I felt for the first time like I could "rest" in awareness as opposed to rest in the talking "self". My head was definitely a little fatigued from my conflict but it was nice for the rest of the day. My next mindful jog I did on the weekend I found it easy to be present but what I didn't expect was that my typical feeling of self-image felt not as all powerful and strong as the mindfulness. The chatterbox in my head felt mechanical and like a tool I could put down and then rest in mindful awareness instead. I really feel like the non-self descriptions are making more sense.
It's like I prefer one to the other so now when I do my typical habits of enjoyment I often feel like I'd rather look at the feelings (enjoyable or aversive) instead and be aware of when it passes away. I used to eat a lot of sweets and the overpowering craving now is something I can watch passaway and I'm losing weight because of it. It's now fun to be in more control. As Daniel describes I did get a bout of stiff neck problems but I've never understood what that is about other than sleeping in a bad angle.

So:
- Irritation
- Non-self
- Impermanence
It could also be more cause and effect because I'm noticing more that I don't surf the net mindlessly like I used to and TV commercials are so bloody irritating. I'm desiring more mental freedom.
