As we all know gambling these days has become very easy to reach all aspects of our lives. You can play at home with online casinos, you can verify yourself without having to get any physical documents thanks to eID etc. You can even play from your bed thanks to mobile apps and mobile friendly gambling websites.
Well the approach is quite simple. Just as those working from home will share a pro tip that they have compartmentalized their work space from their living space to be separate, so they can live the rest of their day before and after work peacefully... Under the same principle it might be best to just not login to your gambling account on mobile.
If you have pressing obligations, if you have a strict budget or limits, which to be real we all do in some way or another, it's best to compartmentalize your gambling also. Only do it at a certain spot on a certain machine. Don't bring it everywhere and don't open up the possibility of playing everywhere all the time.
That's it basically. It's what I do also. For me it's a preventative measure to save time but also prevent addiction or financial ruinage. For others it might be a recovery tactic. Who knows. You can try it or tell us how it has worked for you if you already tried.
The trouble with these sorts of "tricks" is that if someone has enough self control in gambling to stick with this rule, then they most likely have enough self control not to be a problem gambler. It's true that people who have picked up the habit of gambling on their phone, either through a website or a separate app, are going to be more vulnerable to losing money because peoples phones are an ever present fixture in life. You also mention budgeting and limits, which are probably better ways to manage your account, as long as you can resist the urge to remove them or raise them so high as to make them worthless. Letting gambling seep into your whole day is definitely a problem and this solution could help a little.
