I had the same problem. In fact, for a couple of semesters in college I followed the 28 hour day schedule:

These days my biggest problem is waking up too early, not too late.

What worked for me:

1. eliminating caffeine from my diet, saving it for medicinal purposes. Ibuprofen + caffeine is an order of magnitude more effective for me than ibuprofen by itself; but that's because I'm no longer caffeine tolerant. (See #4)

2. No screens after 8PM.

3. Better reasons for going to bed and waking up early. AKA a wife to share the bed and kids to get to school.

4. Getting older. Biologically, 7 year olds & 50 year olds share a propensity for waking up early, with teenagers the highest propensity for sleeping in. You don't have to wait until you're 50, it gets better in your thirties, in my experience.
