I’ve used ambien and that L one. Benefit/negatives = not worth it. My husband and friends switched to trazodone (safer and cheaper) and really like it. I’ve learned to put myself to sleep quickly by focusing hard on relaxing each body part for 3 breaths, starting with feet, ankles, lower legs, … When i wake up in the middle of the night it’s harder, but i can usually do it if i concentrate. Oh, when I’m really struggling, adding cannabis helps.
