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.
Lucky for you mate. Frankly speaking, this was my very first time to engaged in such act of self inflected gambling addition. I have seen many addict's and their end results; this has been my fears of not getting addicted while I gamble but was caught unaware in the act of gambling that caused me #30,000. As you have rightly said, I need to checkmate myself in order to avoid future occurrence.
