TD - mum's is in the wardrobe and she just puts up with the sleep apnoea - she is a very unhealthy lady so this is just one more nail in her coffin (yes, that sounds awful - but I say it as i see it - 9 out of 10 times i call or go to her house she is asleep on the couch)

she is too unhealthy to undergo the surgery that may help her, too lazy to set the machine up (it should be used for all sleeping, so day naps as well) - it's just unbelievable

i would try the machine first and see how you go - i think you can hire them short term. if it works, even if it's only UNTIL you can get surgery... i would do anything i could to get sleep to be honest - yes, being spooned is nice, but sleep is more important to a long term happy relationship...
