I'd definitely at least suggest chugging water and getting crunchy water like apples and cucumbers in you. Also if you drink caffeine less than two hours after you wake up, your body hasn't flushed out the sleep receptors from last night yet and you've gotten them shored up to hit you again later in the afternoon. Caffeine literally has zero energy in it. Speaking as someone who still drinks it but is trying to be VERY careful with the timing (never later than 6hrs before bed time, that's the half life of Caffeine), it doesn't give you energy. It just shuts off sleepiness temporarily, but if you were already sleepy when you drank it you're gonna be sleepy again later. Maybe supplement with those Caffeine-free energy drinks like the gamersupps options for the placebo effect?

(As for the beer, is a little weed an option in your area or is that just trading bad for bad? I had a can of thc plus the other thing drink once and holy damn that was the best sleep I EVER had. Finally shut the brain up.)

Caffeine tolerance is fully gone after 2 weeks without it. Stop drinking energy drinks at all for two weeks, then don't start again. They're nice for special occasions, but I don't think it's good to drink them every day. Maybe drink a set amount of cups of coffee per day or sth like that.

General: Drink a shitload of water and eat green things.

Morning: take a multivitamin, vitamin D, and either sublingual B12 or methylated B-Complex.

Throughout the day: take electrolyte supplements like potassium gluconate, magnesium citrate, or drink Gatorade or equivalent in place of the caffeine. I've tried Liquid IV more recently and subjectively it does feel like it works better than standard sports drinks. Light therapy can also help if your work environment is conducive to it. The good lamps are kind of expensive, though.

Night: limit use of glowy screens for an hour before bedtime or use a blue light filter / night light type application or system setting. Take ZzzQuil, melatonin, and if you're not opposed to it, try to supplement weed for at least some of the alcohol. Indica edibles are the best for sleep for most people. Be super careful with the dosages at first because as Snoop Dogg put it, that shit ain't got no off button.

Do you snore? If so, you probably have at least moderate sleep apnea. Ask your GP for a referral to a sleep specialist. You don't have to stay overnight in a lab anymore, they have a little kit they send you home with. All of the stuff I've listed above is what I tried before realizing the apnea was the main problem, and it all worked to varying degrees. The CPAP has basically given me my life back after decades of not realizing how shitty the quality of my sleep really was. It made the biggest difference, but I still do all the other stuff and most days I feel like a fucking superhero compared to my previous self.

I hope this helps!
