If brew-day is exhausting then you are doing something wrong. this hobby is supposed to be fun, not a drag
my brew day is 4 hours, start to finish, including set up and clean up. You need to simplify (as suggested above) or go smaller. Bring back the fun and remember the KISS principle
You don't have to do 5 gallon batches every time. try smaller batches brewed more often. I used to do 5 gallon batches too, but found myself stressed, dripping wort all over the floor and not having fun...at all.
Now I do 2.5 gallon (BIAB, all grain) batches, brew more often, enjoy brew day, don't need a yeast starter (small enough that a dry packet works just fine), can lift the heavy equipment, can brew inside the house on my stove with equipment I already have, all my brewing equipment (including empty bottles) fits into a cupboard and a tiny closet, no more wort spills and my brew day is 4 hours including set up/clean up and a movie/shopping trip while it mashes. Grains cost me less than $25 and I can brew on a whim and still have a life. True, I produce fewer bottles each time, but more batches means more flavor choices.
