I take melatonin as well - when I know it will be a bad night, I do have Ambien from my doctor. One thing my DB coach said, you have to be mentally and physically strong to get past this. I laughed as said mentally strong, I am a chip shot away from crazy right now!
Take care of yourself. I will keep you in my prayers.
One thing my W and I did a long time ago was put in ICE into our cell phones - ICE stands for In Case of Emergency - that way, if something happens to either of us, officials know to go to the ICE number in your phone. You should at least ask your H to do this and you do this as well. It is a huge peace of mind. My mom was a dispatcher at a fire department and told us about this.
Sleep well.
