"i rarely have trouble falling asleep so that&#039;s not why i use it.  i use it to stay asleep if i wake up in the middle of the night for whatever reason.  there are times when i wake up 2-3 hours before i want to and my brain shifts into overdrive and i can&#039;t get back to sleep, or if i do, it takes me about an hour.  this medication eliminates that.  i only use it if i&#039;ve had a few nights in a row like that. then i get caught up and wake up rested.  i would never feel comfortable about using it nightly.  thankfully i don&#039;t need to.  0.5mg is all it takes for me. i&#039;m 5&#039;3&quot; about 130 give or take 5lbs. a bottle of 30 lasts me several weeks or a few months."
