How do I stop impulse spending and stick to budget?

The most effective method is to create friction between yourself and the purchase. Implement a 24 to 48 hour waiting rule before buying anything not on your planned list. This kills most impulse urges because the emotional high fades quickly. Practically, use cash or a prepaid debit card loaded with only your budgeted amount for discretionary spending. When it's gone, it's gone. Unsubscribe from retail emails, delete shopping apps, and remove saved card details from websites so buying requires more effort. Track every purchase in real time using an app like YNAB or Mint so you feel the impact immediately. Identifying your triggers, like stress or boredom shopping, also helps you address the root cause rather than just the symptom.
