Do you think being disciplined with money and food is difficult?

I bought a bunch of food to eat when my family and extended family go to Las Vegas without me for a week - I was encouraged to go but did not want to because I wanted a one week break from seeing my family all the time. And I was tempted to eat it now cause it tastes so good but I know eating it early will penalize me. Same - I have 5 things I want to buy and buying them all at once will save me the trouble of counting money every week but I know buying it all at once will put me into debt so I might have to space it out for months and weeks at a time.
