I think more sleep is needed but not specifically in one go. Having 8hrs sleep doesn't always make any difference to having 5hrs if it's all in one go. When I was pushing my limits I was sleeping on my lunch break and eating while working. That hour of sleep kept me going much better than knocking off work an hour early to sleep longer.
Getting out of that routing was very hard work though. I could pretty much sleep whenever/wherever, but then getting up was the problem. I could sleep for 16hrs straight if my alarm didn't go off.
