Hi Captain Neo,
Sorry to hear about your personal struggles. I just wanted to let you know that you might be able to find someone to talk to. I googled AA meetings in Tokyo(aatokyo.org), where you might find some support. There seems to be a good # of meetings. Maybe you could try this? and just listen to others and see if anything the people are saying resonates with you in regards to your issue w/alcohol. I hope your doing okay and please take good care of yourself.
