Im sorry for whatever reason we couldn’t connect on the helpline yesterday.
Reading through your thread shows a lot of commitment, and your right as soon as a self exclusion time is up you may well get reminded and that will bring on urges.
Have you considered taking this to the next level. 6 months is the minimum self exclusion period written into the regulations of self exclusion, but the other end is 5 years exclusion with some operators offering life time exclusion
By doing an extended exclusion your remove so many urges.
Another useful tool is to change your email address, thus stopping unsolicited emails that act as triggers
Lastly have you considered gamblers anonymous, Japan has a huge amount of meetings. Over the years Ive come across many English speaking people attending GA in Japan with no language issues http://www.gamblersanonymous.org/ga/addresses
