that's the usual dilemma of most gamblers, even if they allocate some budget to their gambling habits, most of the time, they still exceed with their limits, and so the problem arises. sure, if you can stick to your budget, then you won't have a problem. but how many times do you think you can keep up with such discipline? i believe a lot are going outside their budget especially when they are still on the losing side and they already busted their bankroll.
i guess recording losses is not a very common task done by gamblers. because for one, it is hard to keep up this record. much easier route is to stick to your allocated budget per session. and once busted, stop and call it a day. come back when you have spare funds again. not many gamblers are lucky enough to go home with his winnings, that's the fact. so don't rely on your games to pay for your bills.
