Alcohol tolerance is so damn high

I have noticed throughout the years especially as of late. My alcohol tolerance is so high that It takes half a liter of whiskey to get that tipsy Happy Go Lucky feeling. But by then I’m already on the tired side and I want to get drunker without the risk of jumping to a blackout state, due to the natural quantity of the alcohol already in my system.

I end up passing out way too soon without enjoying the booze and the phases of getting drunk.

How do I enjoy and stay drunk for a solid night without passing out while consuming a lot of alcohol due to my high tolerance

May be a dumb question but I am not ashamed to ask
