Half month has been past, but I am not doing any good both result and volume wise.

So last week's downswing upset me quite a bit and forced me to take a few days break.
I finally came back grinding few days ago.
The following graph shows the results since the short break.
Although the results are not particular good and the volume is kind of suck. I feel like I am gradually getting back on track.
I know there's still tons of area I need to work hard to improve, but overall I am satisfied the way I play most of the time for the psat few days.
However there's one thing concerns me quite a bit, as I have found that the K.O stt has been so reg infested lately.
Few days ago, I just saw 6-7 regs I marked sitting in same game and I ofcoz instantly unreg when I noticed that.
I wonder how those regs bother sitting the games, are they really satisfied with rakeback only?
Therefore, I have changed my schedule for grinding.
For the most part previously this year, I often just grind a 6-8hrs session continuously the day I play.
But now as I have to pay more attention to table select, I have decided to play several shorter sessions in a day instead.
Another reason makes me to decide that is because of my poor quality of sleeping.
Since I have moved to Guangzhou, I hardly have a day that I can sleep well.
Often times I just wake up unintentionally after just few hours of sleeping, so I am not really mentally strong enough for long hours session grinding like I was before.
Would really appreciate if anyone can suggest ways that can help for good quality of sleeping.
As for studying, I had my first coaching session with Glitlr few days ago.
He is just so awesome, the way he talks and the way he thinks about the game really opens my eyes.
I feel that it benefits my games hell of a lot for just one lesson with him.
Highly recommend him as a coach if you are looking to improve your game.
Enough rambling so I will just stop here.
Hope I can sleep well and run good and same to you for those who are reading this.
