Try drinking more water. When I drink a lot of water, I feel that I can drink a cup much later in the evening and sleep much better at night. I highly suspect that the water intake and release washes caffeine away with it (e.g. helps with whatever mechanism caffeine is removed be it filtration, chemical, metabolism, etc). There are lots of other benefits to remaining well-hydrated, I wish that I understood this decades ago.
