I had taken about 2.5 to 2.9 mg sublingual overnight for more than a week but finally got down to 1.2 mg last night about 5 hours after bedtime. I've been taking it for over 2 years. I average 5 to 5 1/2 hours of broken sleep with it. Still not enough. Some people like Mirtazpine, Trazodone, or Gabapentin to help sleep, or might be lucky with OTC meds, melatonin, l-theanine, valerian, CBD, or such - not me.
