Like
iraisejj and
willie beaman (above) it's a serious love/hate thing for me too; and although I try to play tight and promise myself I won't rebuy, unfortunately the lure of being able to get more chips seems to suck me into stupid loose behavior more often than not.
However, in full disclosure mode - although I kind of hate myself for it - I do have to say that I actually won some good money in a tournament after I broke the
No Rebuy promise to myself and took the plunge.
The transition of playing style shown by the friend of
mundybags1 (above) from crazy loose & aggressive to tight and aggressive is the scenario promoted by Daniel Negreanu

Maybe I'll try that some time, but I'm not sure I'll have the bankroll to comfortably do it for a while.
