My arch nemesis: myself

Badly need help on controlling myself not to spend a lot. I know there’s budgeting and how important it is to stick to it but when temptation comes like craving, peer-pressure, and other spectacles, I lose sight of my plans. I tried to transfer funds to bank accounts with no physical card so I cannot withdraw the money, but guess what, my mind cannot be tricked so easily ‘coz I know I can still transfer it whenever I crave food. I planned my expenses almost like monthly only to find myself going back to my old habits of spending. How do you discipline yourself then? My ultimate question is: how do you conquer yourself to be financially independent?
