Picked up a shift and now am looking at 8 hours a day for 7 days straight. Any advice on how to make it through?

Before you ask, money. That’s why.

So I’m pretty competent. I’m both front end and GM. Mainly tech. I don’t do Fufillment at this moment. And energy drinks are making me sick.

I know this was a bold choice, but after this 56 hour streak I will have 4 days off. The money will be good. If there’s nothing that can help me, then I’ll tough it out. But any input would be greatly appreciated
