How do I get my spending under control when I have ADHD or struggle with impulse buys?

If detailed tracking never sticks, lean on systems that require little ongoing willpower. Automate savings and bills so the essentials happen without you. Add friction to impulse purchases: remove saved payment info from shopping sites, unsubscribe from marketing emails, and impose a 24-hour or 72-hour wait on any non-essential buy over a set dollar amount. Use a single spending account with a fixed weekly allowance so the balance itself is your limit, no math required. Turn on low-balance and transaction alerts for instant feedback. Prefer visual, simple tools over spreadsheets you will abandon. The strategy is to design your environment so the easy path is the responsible one, rather than relying on in-the-moment self-control, which is exactly the resource that runs short.
