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. 
You probably need to take a break. People definitely profit from dice but it's not regular profits. Huge wins happen randomly or once in a while especially for luck-based gamblings. You just got lucky with your former wins, I guess.
it's not everyday that you'll have the chance to take a piece from the house bankroll, though there's really a lucky day where you can have big profits but along the way if you don't have the right attitude you'll be going back to lose it again, you need to settle your emotions and make a much deeper assessment to make sure that you'll not suffer from this activities.
If you are gambling with something you might cry over when lost, you cannot take a chance on luck. Luck comes once in a blue moon. Outside of it, the house edge is ruling over you. But if you are gambling for fun and with an amount you are willing to forget, dice is a fun gambling game. Otherwise, you better bet your money on sports matches you are familiar and fond with. Or perhaps some gambling games in which you have the skills.
