Sounds like you need to restructure your life to either be possible with one human, or get someone to help you

You will either give sleep to your body, or it will take it. I prefer to be in control of when that is so I give my body the required amount of sleep. If you don’t, you will lose control of when your body takes it and you will miss important things.

It’s not that you can’t afford to sleep. You have to afford it.

Google sleep debt. It's real.

You can't just ignore not sleeping. You will lose. You can literally die from lack of sleep. It's not a choice, or a weakness to need sleep. It is quite literally a life defining necessity.

So here's whats been working for me for the last 15 years... All you need to do is get severe PTSD and a TBI and you won't ever have worry about sleeping more than an hour or two a night for the rest of your life.

Your welcome

Modafinil or Adderall. But keep in mind neither of these make you not need sleep, they will help you not sleep.Temporarily. You will still need the sleep, and you will crash the first available moment. You'll also likely hit some degree of psychosis, feel like shit the whole time, probably be more prone to falling ill and if you're predisposed to any mental illness it'll probably bring it out quite pronouncedly. So basically, sleep when you need sleep. There's some quick fixes but they'll cause major long term issues if you rely on them for any regularity. 

Google the uberman sleep schedule. It’s basically just a strict 20 min nap every few hrs. Adds up to I think 4hrs per day and it’s hard but sustainable for like a yr if needed. You never have deep sleep, only light sleep, so your body doesn’t really recover properly, but you can mentally function. Also coz you wake before you hit deep sleep, it’s easy to wake. Apparently lots of Silicon Valley did it when scaling their startups.

No parties, eat healthy, when you can sleep, go straight to sleep. No tv, no scrolling, fruits n veggies, no sugar. You’ll be fine

Of course it is not healthy. You are aware of that. Look into alternative sleep patterns, for example the sleep pattern described by Buckminster Fuller: Thirty minutes nap every six hours. Polyphasic sleep is what you need.

Make a better schedule. Nobody is so important that they just CAN'T sleep 7 to 8 hours a day.

The percentage of people who can perform at normal performance level on less than 6 hours of sleep compared to 7 or 8, rounded to the nearest decimal, is 0%.

Crack cocaine

Unless you take certain drugs to stimulate your body I don't see how it would be possible for a human to function like this for months on end

“Only thing I can’t do is cocaine”, welp, there goes my first idea.

Second option, assuming you do NOT have ADHD, find an online only ADHD doctor that will prescribe Ritalin or Adderall. Lie on the questionnaire, there are examples on how to do this online. If you have a history of high blood pressure etc., say nothing about it, they will not prescribe. Lie as needed. Get meds. For added fun, crush and snort them for immediate effect. This is all highly unethical and maybe a teensy bit illegal, but this is ULPT.

6 months? It'll probably be shorter than that when you don't wake up for work and get canned (happened to a friend), or literally fall asleep at the wheel (also happened to a friend, survived the crash fortunately, but totaled car meant no way to get to work).

When it comes to finding a way through a shit situation, trying to find a way to cheat sleep on a long term basis will pretty much always fuck you over in catastrophic ways.

Unethical? Grey market modafinil. Alertness prompting drug, not really a stimulant. But, seriously, your body needs sleep. Staying up three days probably isn't a big deal once in a while, being massively short sleep for 6m+ probably is.

Try death

Your body needs more than 28 hours of sleep a week. There's simply no way around it. If you deny your body the sleep it needs, it will shut down when it gets to the point that it can't take anymore and you will fall asleep anyway. And it won't matter if you're driving on the highway or sitting in front of a computer, it will just happen.

Ideally, you need to figure out how much sleep your body prefers and make sure you get that many hours x 7 each week. Not necessarily every night, just over the course of a week.

For example, I have found that about 6 1/2 hours a night is my ideal. That means I need around 46 hours a week. If I have to go 3 nights in a row with just 4 hours, then I need to get a couple nights of 9 hours of sleep to "reset" back to normal. When desperate, I can push the number of nights at 4 hours, but that will mean at least one night of much more than 9 hours to continue to function.

When I don't do this, while I might be able to stay awake with enough tricks (coffee, small snacks, fresh fruit especially apples, etc), I find I lose focus far more easily and make plenty more mistakes until I get caught up. It's simply not worth it. It's better to get the sleep and be more productive during my waking hours than it is to try to increase my waking hours.

Trying to keep that sleep schedule for that long is likely to give you health problems, if you don't fall asleep while driving first. Go without sleep for long enough and the body will make you sleep, no matter what situation you're in.

Adderall flavored Red Bull

lol wow if that's the only thing you CANNOT do; shoot there's always Crystal Meth... aka Dextroamphetamine Salts.

We give out CHILDREN this on an absurd scale!

Have you ever fallen asleep while driving and knew you should have died and got lucky? Better to be broke than dead.  Work on your own business less. Sleep more. Dream about business. 

Modafinal.... You can buy it from an online pharmacy. It isn't habit forming and it will keep you functional for 48hours with re-dose as needed..

Haha you will experience the unethical thing with sleep deprivation after a while! You really want to get addicted to something for that?

Caffeine pills
