What kind of things can you do to wake her up more effectively? Ice water worked on my gfgbro, and he is notorious for sleeping through everything AND waking up swinging his fist. It was a reflex more or less and done with-o him being awake. By high school he had decided to hate beds and he slept on an old couch instead. That made it easier to pour ice water on him and not get hurt when he swung. My mom did the ice water first, and then when it was the ONLY thing that worked, gfgbro paid me $5 to pour it on him each morning to get him up and moving. I kept a bottle of water in the fridge and added ice to it in the morning before I woke him up.
Yes, it makes her MISERABLE and ANGRY in the morning, but isn't that how she is making you feel? Sometimes a taste of their own actions is needed.
they also have alarm clocks that you have to get up and get to shut them up. I bought a knocked of the one with wheels on either side that literally would run across the room from you. It was loud and it got louder the longer it was on before you stopped it. I have also seen some that are helicopters that fly around getting ever louder until you catch them. I think that wouldn't last very long.
You may have to get firm and put some negative consequences in place, such as if you don't get up and moving the first time I tell you to, then I pour ice water on you. It won't take much, or you could just rub an ice cube on her, Either way, right not most of the stress is on you, and more needs to be on her, in my opinion.
