Narrative:

I was junior manned on my second all nighter in a row in 2 days. I can honestly tell you that it was an unsafe situation having me in that cockpit this morning. I would not have been able to shoot an instrument approach; had I needed to. First of all; it was my second all nighter in 2 days in a row. Secondly; there is a 2 hour 50 min situation in ZZZ1 before returning on the all nighter. If we are on the verge of losing this airline on the next accident; you better decrease the situation times on these all nighters; or not make people fly these back-to-back. I hope you take this seriously; as I did; knowing how dangerous a situation this is.
