Sure, the side effects are what are important! I treat them like pointers or flags of where to dig for the treasure :-)

I sat bolt upright in bed, like about Midnight one week because I suddenly realized I hadn't given the check I'd already written to T. At the end of each session it would make me anxious if I had to write the check while she sat and waited for me to write it so I'd make out the check before I went (usually, not always) and just give it to her at the end of the session instead. Well, I jumped out and bed and looked in my wallet and sure enough, I hadn't handed it to her. Well, that just made me think back to what we had been talking about and I'd been angry with her! Eureka! It was wonderful, here I'd unconsciously not paid her because I had been angry and not realized that at the time either but did now. I couldn't wait to get to my next session, called her and told her I had forgotten to pay her, asked did she want me to mail it or write her a check for twice as much the next week, etc. She reassured me next week was fine and we "rejoiced" when I told her what had happened.

It's the little things that can be so important and which come first and "build up", not the huge epiphany, assuming you ever even have one.
