Gambling and trading is same thing , risky game but trading is better because it can't be as addicted as gambling AFAIK
Religion really play the main role for people's mental recovery against addiction but it's still need time to fully recover !
you can go for trading as an alternate to double your money with less risk and maybe a little bit make you headache with its volatility. gambling really not recommended for those people who have no discipline and irresponsible . just treat trading as game of guessing at first impression , sooner or later you will get used to it.
