gameplan for downswings?

[ssnyc]

I've had a very good poker year and done very well in MTT's...ROI high with a good number of wins...November however has been my first really awful month and unfortunately I've had the time to play a very high volume too...the good news for me is that I'm a bankroll nit so even the bad run hasn't done a huge amount of damage...

my question is when you are playing well and still losing what is the best game plan...
