Low Stakes Bad habits

[playerfl]

I have realized over the past few weeks that many of my mistakes are the result of bad habits picked up at low limit games. I read an anecdote in T.J.'s book on PL and NL holdem where he talks about a player that plays his "A" game for about two hours, then reverts back to his ingrained "B" game which isn't good enough to win long term. I think this is the situation I am in at present.

At first I thought I was just fishing out due to fatigue, but now I realize I am reverting to habits built up during the first 6 months of my poker career which actually worked when playing with bad players at inconsequential stakes.

I would like to hear from anyone with a similar problem and what they have done about it, or are trying to do about it.
