Try this...IF you are compelled to have a bet, have seperate and distinct accounts. One account is for the serious stuff, the other for when you have nothing better to do......

The other suggestion is to use your idle time to make money rather than lose it. Put your Sky to good use. Instead of backing the horses you don't know much about, get a notepad and record the unlucky runs, the bad rides, the fast finishers, the rogue barrier horses, the horses that look like they've had enough etc etc.

Then when they next run, you're more informed and more likely to make money.

There are several blackbook services on the net that will auto alert you to an upcoming run.
