Repipe from hell

My first big job as a journeyman has really sucked. It's a total repipe with about 6" of clearance and a completely separated sewer main. I bid this at 7 days of labor and my forman is getting pissed that I probably won't be done in 5... We spent the frist two days digging in and yesterday I got the majority of the water replaced. Today's goal is to finish the water and start ripping out sewer. There's a chance I can finish by Friday and I'm going to try like hell but I doubt it. My budget is looking fine, not stellar but it's coming out to be really close to what I wrote up. I really want to do good but this is hell. I'm just venting and trying to convince myself not to just flee the country.
