Looks like my post got take down, so here it goes again.
Like I said before, this is completely unhealthy (not just the drinking per say). You need to take control of your life, and your finances, better than this. You've already explained your financial difficulties in your other posts, but when you come into some extra money you're literally peeing it away???
I get wanting to blow your money on something fun, but have you already forgotten how much difficulty you had in even making this first payment? What about next month's payment then? Sorry to say, but instead of blowing that money you really should have put it away, especially knowing you'll need it very soon.
Look, I'm not saying this to be mean, but if you don't start taking better control of you life, and your money, then you're headed to either become homeless or a suicide statistic. Neither of which anyone here wants to see.
