Have anyone profited out of dice in the short or long term. I have been trying the best and lost all, I can't leave it. Once after I loss I have gone beyond my ability. Finally as the wallet got emptied, I bought bitcoin particularly for betting and lost even the amount earned from my day job. I used to experience win, but at the end it is a loss. I miss the right time to stop and leave. 
At least now you know that the dice is might not be the best game for you. You could try other games like poker and other card games. But if you prefer dice games more, you should reevaluate your chances on winning on that. In card games, you can train and have strategies that can minimize your loses. But in dice, nothing will stop you unless you'd emptied your capital.
