It might be worth trying different kinds of tablets but the lighter one can run out by about 4am so you might have to take them again.
Sometimes I just give in to it and get up and make a cup of tea and watch TV a bit. Then I sometimes fall asleep about 5am. Luckily it doesn't matter what time I get up but I prefer to get up by 8ish.
If you try all the usual things together, winding down, no drink after 9pm (or even 8), hot bath half hour before going to bed, making sure the bed is comfortable etc. it can make it easier but I find most things only work temporarily.
People do sleep less when they are older. If I go to bed early, I wake up at 5am.
