I have had the same problem and something that has helped me a lot is practising with the short 4 sided dowels and an impact bag in front of a mirror (or a glass door/windows at night). I have a sliding glass door in my basement that I use at night.

Go into your setup and align your nose with a mark on the mirror/glass. You can use a natural mark in the glass/mirror (like a panel or something), or put a small vertical piece of masking tape. Then go to the top and check to see if your head is in roughly the same position. You can also check after you hit the impact bag.

After many, many repititions of this I am seeing progress with keeping my head steady. The visual feedback definitely helps with this.
