How do I wake up tomorrow morning without subconsciously turning off my alarm?

I have a horrible habit of hitting snooze repeatedly, or even turning off my alarm clock completely in the morning. I have almost no memory of doing it and no matter what I've tried, I have been unable to stop. I know that getting more sleep, or sleeping earlier is an obvious answer, since this occurs more when I don't get my 8 hours but I don't have that option tonight. By the time I get home and in bed, it will be midnight at the earliest, I'll be sleeping by 1am and I need to be up at 6 sharp.

I have tried the alarm clock across the room, but found it unplugged the following morning, ive tried setting multiple alarms and sometimes that works, I've tried drinking a ton of water before bed, but that's not super reliable. What else is there?
