Luckily I have never lost sleep over gambling. I've always gambled within my means and kept my bets semi-low. If you're having trouble with gambling and losing sleep over your losses it's time to take a step back and re-evaluate your addiction. Please, if you're spending money you can't afford to lose, get some help or counseling for your gambling.
That was a good advice bud, I don't understand why there are some gamblers who willing to risk their money if they can't afford to lose it. And now, the difficulty of sleeping just because of gambling. In my part, I always gamble at my convenient time, or else that time that something I am getting bored. This is like you are chasing money in gambling and even during your bedtime, you are still thinking about gambling. You have full control of your self, don't let gambling will control your mind.
