I'd like to plug going part-time as a good way to temper burnout and provide a soft landing for if/when you eventually decide to leave. You still get some money coming in -- proportionally more due to progressive taxation. You still have benefits, which the company may or may not still cover as if you were full-time. You avoid abrupt life change while getting a four-day weekend every week. If your company values you they will probably be more open to this arrangement than you may think.
