Welcome Easyrider. I know exactly what you mean about changing the drinking routine.
I've had so many great ideas to fix this.
It's the whiskey, try rum. Drink nothing more than 20%. Only buy a small bottle. Drink a lot early, to get a good night's sleep. Only drink more expensive wine, not the cheap stuff. Etc etc.
The only foolproof plan is to not have the first drink. And as Dee said we have to really really fight that urge when it comes.
A bit tough this evening, but just finished the last of the ice-cream and will now watch the English news.
Good luck and take care.
