I've been an insomniac since i was a teenager, but it is so much worse since chemo - especially on paclitaxel. My partner also snores - we moved in together half way through AC chemo. I could use ear plugs before, but on paclitaxel they give me headaches.
I use a sleep app on my phone called 'sleep time' it has different soundscapes - rain forest, thunderstorm, etc
I also set up the spare bed so that i can sleep in there if i am really struggling, also so my tossing & turning doesn't wake him up. My mattress has a pillow top as well as a lambswool cover. My Oncologist gave me sleeping tablets as well as endone for the bone pain. It helps somewhat, but other nights, (like last night) my arthritis will act up & i struggle - ended up in the bath with my feet under a stream of hot water at 3.30am just to stop them aching (i'm nearly out of endone with a week to go til i see him next). The hot water definitely helps at times like that. I need to get a proper massage or something soon though as I am just aching a lot at times.
The soundscapes give your mind something to focus on instead of wandering & over thinking anything else., allowing sleep to come.
