Looking for a Tony time-travel fic Post-Endgame
This is my first time posting so I'm sorry if I did anything wrong!
So I read this fic on AO3 a while ago where something goes wrong with the snap and Tony is the only one left and everyone else got dusted. Tony then realizes that the only way to fix everything is by going back in time. The details that I can remember are that he's drinking right before he falls asleep and then he wakes up in the cave in Afghanistan and knows exactly what's going on. I think it may have been removed as I can't find it, but if anyone knows what I'm talking about I would appreciate a link/title! Thanks :)
