Same. I worked them as 3-3-4-4 (3 on, 3 off, 4 on, 4 off) and even still, it was taxing. You get extra-long weekends all the time, which are basically mandatory, because you spend that entire first day recovering from the previous 12-hour shifts. Though it also switched between days and nights, so you'd end up spending your last day adjusting yourself to the upcoming "time switch", which further worsened it. The company had all kinds of research indicating that it was great for morale and productivity and such, and they had a strong union that didn't seem to hate it, but I always had a hard time adapting. I can't imagine doing it for 6 days straight.
