Sleep issues

I'm on a 2 day waking up for Minyan in the morning, my alarm goes off at 6:30 and I'm there by 6:45. Here's the problem, it's been a while since I set my alarm, now I wake up several times pre-alarm and check what time it is. This morning, I think I checked at 4:30, 5:30, 6:00 and then I got up a minute before my alarm went off.

I think it's because when I'm falling asleep I have the mindset that I want to get up before the alarm goes off so I can shut it off before it wakes anyone else.
