I recommend a large bludgeon for this, so that it may be applied and then laid aside in fairly short order.
The bludgeon: We are reasonable people here. If you have living requirements that specific and inflexible, perhaps you should find alternative living arrangements where you don't have shared housing. Now, shall we talk about suitable compromises inherent in shared housing arrangements?
Heartless, perhaps, but it gets straight into it without preamble, and doesn't allow for the hour of continual pounding, since it moves straight into the 'how do we compromise' area, and keeps the blame stage mercifully short. She's not bargaining from a position of strength here - it's a lot easier for you to make her miserable, than the reverse, since she's the one asking for special allowances on her behalf. Her ability to make unilateral demands is pretty non-existent.
