Maybe you are experiencing rebound insomnia since you were using marijuana nightly for a few years. That is common when using any type of sleep aide. Your body becomes reliant and when it is taken away, your body has a hard time remembering how to fall and stay asleep. I agree that smoking is not a good habit for your body, but have you tried CBD/THC gummies? I read a study by the CDC that suggested up to 80% of people get help sleeping when they try this combination. However, like everything else, you can develop tolerance and dependence. I have had insomnia most of my life and I'm 65. I got great help taking 1mg of Klonopin at bedtime for 12 years and it was taken away when I turned 65 (slow taper) and I had horrible insomnia. I did all the behavioral things and Gummies were of some help, but not consistently, so I went to a Sleep Medicine Neurologist. Her belief was that we all need adequate sleep no matter what our age and if we aren't, there is a place for medication. I am now taking Lunesta and I am back to sleeping. Just stay on your journey and don't accept not sleeping. Insomnia has some of the same side effects as the medications that can help. I am a different person sleeping and all for the better. Good luck.
