Death happens at around twenty four hours due to the way that the slave-ring (what the Qwardians actually call them) overclocks part of the users brain, causing a fatal haemorrhage. The last hour isn't exactly fun either. Since the overclocking effect is always 'on', using the ring less doesn't help. That version of me began frantically trying to track down forms of enhanced regeneration in the hope that one of them would stave it off. The first episode ends with him dying in Nyssa Raatko's living room.
And here:
Suicide. Nyssa suggests a carbon monoxide inhaler after she sees how painful the last hour is. I mean, he knows he's going to die and resurrect anyway, so why go out the hard way? He also has to scout out new Lazarus Pit locations for her and eliminate the rest of the Society of Shadows. He also has to train for fighting Greenies, both because the ring insists and because he has no other way to charge. Beyond that I haven't really thought about it.
