Ambien is effective, but I couldn’t take daily because it’s less effective if used often. I didn’t experience the same with mirtazapine. The mirtazapine was pretty effective alone, but made me hungry and I never used more than 3 days in a row. My PA just rotated. As long as you don’t take Ambien er, I think you can cut it, I just don’t think taking 1/4 if you take it a lot will do much. I don’t know though, not an MD. I have gone off Ambien and onto mirtazapine with no taper. Quvivig is a new sleep med , less powerful I think. It has helped me more with the startle reflex I have. It takes time to do that.
