In my experience (~80K hands), NL25 is pretty much a value betting clinic. Cut out the fancy stuff, and make sure you're getting maximum value. Default with TPTK type hands should be bet/bet/bet, rather than a street removed for pot control.
I'm also having trouble dealing with the swings, as I took August off and in my first 5000 hands at NL25 I'm +/- 0.
