Maybe rather than go cold turkey, wind back your punting frequency to once a fortnight, or once a month.

If you want to save money, rather than punt, then take away the temptation: move your money to a high interest savings account, and limit your "ATM accessible" account to a few hundred bucks, just enough to live off, but not enough to spend money unnecessarily on punts.

That way, there is a "friction" in accessing your money which may help to remove the temptation, especially if you wank to remove the sexual urge component.

For me, the main temptation is if I am out in the evening, the natural temptation is to make the most of it by ducking off for a quick dirty hour. I leave the ATM card at home when I am thinking with my big head, so my little head is not able to make the decision later in the evening

It's hard to remove the temptation, especially reading about some of the hot horny encounters some other bros are having, but the best way is to wind back gradually, and make it 'harder' to punt.
