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.
I was never lucky with my games, it continued for so long and I noticed taking a break was really necessary, did this and I later came back better. I was amazed at the first game I won after my return and it was as though the break time did a lot of amendment, and maybe you should also try and give it a trial and you will be glad you did.
