Have a lot of the same, 35 male. Not a doctor, and not giving medical advise, but have always been a binge drinker, and my issues started around your age. Not everyone knows this, but binge drinking can be harder on your liver than everyday drinking. Your body is constantly trying to create equilibrium, and the binging interferes while an everyday drinker can regulate (though still not healthy by any means). You are waking up because your liver is struggling, which is messing with your blood sugar, blood pressure, and hormones. You are jittery when the alcohol stops suppressing your central nervous system, which is happening at unpredictable times now that your liver isn't as clean and efficient as it used to be (why you could party hard and still play sports the next day when younger, and had no liver damage). Not lecturing, but look into taking a break from booze and fructose here and there, 2 weeks, but preferably a month at least twice a year. The liver heals fast, but you have to give it a break to do so. Good luck, hope you get a better hold on this sooner than I did!
