insomnia
"Been taking the 10mg until it got discontinued and now have the 5mg. I take a whole mg with a half 5mg and this works perfectly for me.  I haven't had any weird side effects and have been on this med for 12 years.  I take it on a totally empty stomach and after about 15 minutes I have a snack before bed if I happened to have missed dinner, After snack, off to bed.  Ambien is my best friend. I am in my late 60's."
