You should really consider a different advisor. In my experience that is by far the #1 most important factor in how your experience will be. You will be putting yourself in their hands much more than you already have. It's entirely possible to have an enjoyable experience with someone who supports a healthy work life balance. Of course when crunch time hits there will be very long crazy days, but when that isnt happening a good advisor will give you space, let you work when and where you want, and not engage in toxic behavior.
