No consultation but rather the casinos will just force you out of their circle. In online casinos, it means no email related to their service will be sent to you or possibly add the account to the restricted list. However, this will be useless as gamblers will do anything to return no matter what and there are lots of gambling sites aside from advertisements that we see on social media.
The best thing to do is not truly stop but become responsible as always even in an event of huge loss.
If the gambler is able to stop, then it is a fair thing to go for it. By the time he can divert and focus on something else that could let him understand life as well as the consequences of gambling in a better way.
