I'm unable to stop playing when winning

[RiverPlay]

I think I have an addictive personality, and Im the kind of person that likes to keep on doing what it's pleasurable for me.
This is my best month ever since started with poker, in agoust 2006 I deposited 40 dollars, and played a lot of 2NL, moved up to 10NL, and Iwas pretty much a very bad player that thought he was good. In february I won 1K (fisrt) at a 5$ tourney and a couple of days latter I finished like 4th and got another 400$, I played some 100nl got quickly up to 2300$ and then started to have very swingy sessions, and felt frustrated because i thought I should beat the game, i hated poker, etc. One day I won 10 BI at 100NL (from 2AM 12pm), lost two to bad beats, tilted hard and lost another 10 BI (from 4pm to 24 am, very tired and confused). That was a crisis, i had only 900$ in my BR. Loosing like 1400$ was devastating (I live in Argentina so every dollar is worth 3X for me).
I decided I was bad and that i had to learn from 10NL from 200$ and build my BR again while keeping 700$ online but just as a saving) I did it from 10NL to 100NL from april, playing solid and disciplining myself, not chase any looses, stop playing when doing dumb stuff, being more focused, etc.

On thursday nigt my girlfriend calls me and tells me she is not coming because she has to take care of his mother, so I decided to play an all night session from 11PM, things went well, I was quickly up a couple of BI's etc... at 6AM i was up 6 buy in, making great calls folding big pairs, getting paid at the river etc... Why would I stop playing?? I made like 1.100 us$, which here is like saying 3.500$ (already won another 1000 us$ during june)I feel like I've been introduced to some kind of moneymaking machine, and that I should stick to it while its working nicely, like if waking away was a crime.

I kept on playing, at 11 AM i was 7.5 BI up, at 1PM 8 buy in up, and so on till 1PM, like 25 hours after i started playing, now 11 buy in up. I decided to quit in the middle of a big upswing with no signs of getting any worst, and i feel i shouldnt. I feel that maybe on monday I will run bad, or that maybe I'm facing softer competition because its a friday, I haven't sleep in 30 hours but I dont feel that tired and i know i play my best poker after being playong for at least 1khands, wich sometimes I'm not focused enough to achieve...

How should I think about this issue? How do you manage it?

I hope the text its not hard to read beacause english is not really my language. Thank you.
