I haven't slept for 3 days
Why haven't you slept for 3 days.
I'm working on my new app and I want to make sure it is  perfect with no bugs.
I know you want to get work done, but not sleeping is bad for your health. Take some time off and sleep.
I would if I could figure these bugs out.
You may end up making more mistakes than corrections without sleep. You are going to prolong your work because of it.
