In The First Day, "10 Seconds Rule" Had Become Failure.

After I made "10 seconds rule", that I bear for 10 seconds when I have my impulse to eat and drink, I failed in the first day. After working, my craving was terrible, I paid over 3000 yens although I decided my budget to 1000 yens every day. Particularly, I bought 4 non-alcohol beer. Does it mean that my craving is such terrible? Even now, I always want to drink alcohol. I decided my budget for eating and drinking as 30,000 yens, but even it's just barely. After my parents pass away, can I make my own living? I have to reduce my money of investing because my budget for eating and drinking has increased. Even now, I become emotionally unstable easily. So I want to take alcohol. It's anti-effective. Can't I change my personality becoming emotionally unstable easily?
