That makes no sense. Why would you only go once in a blue moon to get months worth of expenses and just stop playing till your money runs out? Why not continue playing full-time and earning (by the sounds of it) several hundreds of thousands if you played full time? This makes more sense and surely be a nice living if you actually can do it..
I'd of thought you would of had to keep on top of your game aswell and getting better and better. How on earth do you not play for months on end and still manage to go back to the casino and earn 3 months worth of expenses?

I smell something...
I'm not being funny when I say this and hats of to you if you actually do, do that but for someone to start playing for a living to just play maybe 4 weeks in a year and those limits seems a bit ridiculous. Anyone who can beat such limits would be playing most weeks in my opinion.
ps: Why not go online and play some? Or just play for one year everyday, you could make even more and be a millionaire within a year, get interest on your millions in the bank which would cover all your expenses and you would never have to do it again!

You could then warrant just playing 4 times a year for "fun" and an extra bit of cash to your big stack of millions.
