For the time being, to help mitigate the issue for however long you must suffer this, you can consider locating a professional who makes custom made (therefore not painful to your ear canals, but definitely ask about this) "musician's earplugs". They won't be cheap, my guess is $80 + or -, probably +. However, higher cost doesn't mean they will necessarily be better, it is about the person's skill/experience in creating the mold and plugs. The ones a previous musician I worked with had hired more than one person for making these, and it was actually the lesser costing pair that were better made for him; he found her at the NAMM show. What were also very cool about them, besides being anatomically fitting, were that the SPL levels of protection were totally interchangeable; there are these tiny, tiny little modules you pop in and out of the earplug itself. 15 db protection, pop em in, or say you want to go to a crazy loud concert standing right next to the speakers, pop in the highest level, etc.
Also, they are called "musician's earplugs" because they have a flatter freq response, so those rock concerts can be more enjoyable while also still protecting your hearing.
I like the Serenity Mat idea from above, if your room is very small, a couple of the largest rugs from IKEA are not terribly expensive at all. I mean, if say you were okay with the ugly compromise of the Mat at only the extremes of the room. I'm sure compromises are easy to make when it's good sleep we are talking about. I also wonder how acoustic cotton compares to the Mat, in both dialogue suppression, as well as value (definitely cheaper in bulk). I would definitely ask acoustic professionals, and not me.
