My experiences with EE has been quite steady during the last six months. There's usually some experience with time going faster, where I realize that i just finished the whole pipe breath section, even it feels that it hasn't been that long time. There's sometimes experience of cramping in my legs, detox symptom I guess. After doing the full program, twice a week, everytime I feel refreshed and more in control of my actions. I usually let my mind wander during the breathing (except in the PotS I try to concentrate on the prayer), hoping that my unconscious knows what to do.
