When I switched to methadone alone my sleep improved immediately and dramatically. I was gobsmacked.
It was the DAs, as I had always suspected.
From my reading, both can cause issues with sleep architecture; however, experience has shown me that it is dependent on the person.
Other things that you might want to consider to improve sleep quality are meal timing, circadian rhythm (awake/sleep time), light exposure; and room/body temperature. Adjusting any of these factors can help improve sleep quality in the long run.
