I'm right there with you, and should probably sticky this post to my monitor
Naturally I'm lagg in style, and having started playing a couple of months back with a $100 BR, managed to halve that in a week. I then found FTR, got SSH and read it (twice!), and turned it around. Sticking to discipline (mostly), I got it back to $100, then $140.

Then last couple of days, I started multi tabling SNGs, because I was too bored with playing just one. I added a couple of tables of limit, no limit, whatever, and went back to being too aggressive (both pre and post flop).

Oops - I'm back right where I started

So yeah, my mantra now is: DISCIPLINE, DISCIPLINE, DISCIPLINE!
