Experiencing some of the same. I had a NL session yesterday in which I got KK twice, AA twice, QQ twice, and flopped trips a couple times, and got paid off almost everytime--quadrupled my initial buy-in after about 200 hands. After that run, I started to loosen up to bully and surprise people and never tightened back up again. I didn't get burned that time, but later realized that I was raising KTs from EP, and playing at around 30% VPIP.

My committment going forward is to review my last sessions hands just before starting my next session. When I've done this periodically in the past, it puts my head on straight...
