Use alarms and your calendar religiously, alarms for unmissable events, calendar for every appointment. Use your phone for this, you're probably addicted to scrolling or games on it anyway.
Exercise and get good sleep. Caffeine helps but isn't as good as ADHD medication.
Remove distractions aggressively. Don't beat yourself up when you fail; expect it and move on.
Use people in your life to help be your executive function for you. It isn't really fair on them but if they love you they may be willing to anyway. A gym buddy or sports team is another way of achieving this without needing them to love you particularly.
Block all the sites you lose hours to, aggressively. You're not smart enough to build a system you can't get out of but you can make it high friction. Same for games or media or whatever it is.
Pair programming is tiring but it works for using an external party as your executive function. Keeps you on track.
Negative external consequences are motivating but stressful, use sparingly.
Try find a job with or structure your life with enough variety to keep you entertained; I find people to be stimulating but YMMV.
Medication is far more effective than any coping mechanism.
