I am a control freak

and for the past few months I have constructed a very rigid schedule to try and get my symptoms under control. I have avoided doing anything that changes my schedule and might make my symptoms worse. I eat a similar meals at the same time, I use my 10's machine the same time, I meditate the same time, I get in bed the same time, etc. To a degree this has helped and I do know as far as sleep there is much written about maintaining a regular routine. Unfortunately this has caused me to say no to opportunities, especially nighttime ones, even if I am feeling well.
Yesterday my friend called to offer me a free ticket to see "Swan Lake" with her. I surprised myself and said YES! It was beautiful and we had a marvelous time. I did not have any symptoms at the performance and even though I didn't get home until late I fell asleep quickly, only got up 1 time to apply some lotion and slept the rest of the night symptom free.
I'm thinking my mind plays a bigger part in all of this then I have realized
