Money spending issue!

I’m 17 and although my babysitting jobs bring in a good amount for my age, I am a horrible spender when it comes clothes, makeup, etc. I was not too spoiled growing up, in fact, my parents would never let me buy anything (even clothes!) without my own money that I earned to spend, which i’m not complaining because I believe this probably helped in the long run! However, I feel like since I actually have enough money to buy everything I want now, I have 0 impulse control and immediately add it to my cart. Has anyone ever gone through this before?? Any tips & tricks on how to stop the impulsive money spending??
