This is how I sometimes feel when I gamble. When you bet small, you're winning but when you start betting higher amount, it seems the world is against you. But I know, it is just a coincidence. Not addicted here also. I just gamble from time to time, to pass the time or if I have extra money. So there's nothing to worry about the limit of my gambling time as I can still control myself when to stop, that is usually when my extra funds are already depleted.
This is very common which is why some feel they are begin cheated when they gamble with important sums of money when in reality what is happening is that when you bet with an amount of money that it is small then you do not really care too much about your losses as your capital can absorb them but when you bet with a significant amount of money and you lose that money then you are not happy about it and suddenly some players being to think they were cheated when that is not the case.
