Medical cannabis vs Ambien?

I am 75 years old - using 5 mg of Ambien (successfully) at night to help me sleep for six hours. I have chronic neuropathy pain in my feet , ankles and calves. I have been using for about 12 years and it lets me sleep through pain for 5-6 hours. I am tired all the next day. Cramping pain in my legs and feet usually wake me up or assuming the 5 mg of Ambien are leaving my system. I used to wake up refreshed and able to take on chronic pain for the day, however now I am so tired the next day. I would like to wean off Ambien and try pill or edible cannabis hoping this would work equally or better and give me more energy next morning. Thoughts? Any insights? Thanks!
