working almost 19 hours every day with 3 hours to sleep possible or not?

Question

Hello everyone,

I am currently working at a daycare with toddlers 35 hours a week, I recently took extra work working as a 3rd shift supervisor but is only for less than 2 months after that I can go back to sleep my normal hours.

I really need the extra money but it's going to be very exhausting, I took a week off from my day job to start working the 3rd shift so right now it's not too bad, however after my 3rd shift ends today I need to go to my day job and do the same thing till Friday. Now I was checking and I'll be able to sleep for 3 hours every day until the 3rd shift job ends. 

Can I survive this? it's only until January 18/2021 

Any tips?

Thanks 

Update:

I work at my day job from 7:30am till 4pm I’ll get home by 4:40 right to sleep till 8pm to shower and be at my 3rd shift at 9pm till 6:30am. I do get Saturday and Sunday free to sleep all day but I’m just concern about the week. One coworker told me he sleeps 3 hours a day and his body got used to. In my case I will only do this until the second week of January. 

Answer 1

Possible for a short time like 1or2 weeks, but for a long time it's impossible 

Answer 2

I don't think so.

Answer 3

You can't do this. Doing it for a week is one thing, trying to do it for nearly 2 months is quite another.  By the second or third week you will be so exhausted that you will be making mistakes, be short tempered, and could even cause an accident.

Answer 4

I never worked 19 hours a day in my life. But I did have a number of 13 hour days for a few months. 13 was not sustainable for longer than a few months even at a young age.

Answer 5

I don't understand your math.

You work 7 hours a day with the daycare, if you work M-F

And you aren't working 12 hour shifts 5 days in a row at the other place....

Even if you were, this would give you the full weekend to re-coop.

Answer 6

Your brain cannot function properly only three hours of sleep a night over weeks or months.    You have no business driving a car or taking care of other people's children when you are chronically sleep-deprived and probably hopped up on caffeine.    You literally could kill yourself or someone else.

If I were your employer at the day care and knew you were doing this (or if I saw a change in your behavior indicating such), I would fire you.  

Don't you have any care or concern for other peoples' safety?
