I am one of those who sleep very little. Usually waking up every 90 min. Using medication has enabled me to some nights go back to sleep. I’ve seen sleep specialists, been on various meds but it makes little difference other than mostly being able to go back to sleep. Currently on 150 mg of trazadone but don’t like the side affects. I’ve been this way most of my adult life (78 years) and don’t expect it to change.
