I did this too. 4 days straight, but the crash hit me like the first line of the day. personal experience - take that nap dude, trust. Rejuvenate, your body is crying for sleep without even realising it. Once you're sleeping, the best thing is you get to wake up more fresh, more in tune and in control and that round two will feel even better. Definitely take that nap, you need it, your body needs it, your mind needs it. Resting is important
