One thing I thought about, even with a full lived experience of 30+ years, wouldn't another problem be that once you are back, this life would be but a dream? As in, you could only look upon this current life like you would a dream, and not as reality? Plus with even knowing the outcome of potential situations, wouldn't things still in the moment emotionally distress you to some degree? 

I feel like if this happened many people would probably think of their old life in the future for a week or so and then possibly largely forget their future life anyway, with their present life taking over their consciousness. 

I feel this way in part because when I was abroad for months I felt like a different person, knew nobody, etc. Then when I came back home within a week everything is back to the mostly negative normal of home.

Of course. Randomization still makes a huge swathe of things play out incredibly differently. 
While some things always seem to repeat the same old way, no 2 livethroughs are ever entirely the same.
