OHi Stephen, well done on looking for help.
So, I am assuming you do want to let go of gambling this time? If so maybe try GA again, you might be ready for it now.
Your brother could help with accountability, with internet banking we can be accountable to someone even if we don’t leve in the same area.
Where do you normally gamble? Get yourself banned.
You are on holiday for a week – plan that week. Fill your time and thoughts with thigns away from gambling. Only carry the money you need on a daily basis.
Keep posting.
