Hi Jennifer,

I've taken Unisom but it has been a while.  Unfortunately I can't tell you a 
lot about it except that it is sold over the counter and can help one stay 
asleep.  It would probably be wise to speak with a pharmacist to find out 
about the effects of long term  usage.  I don't think it's considered 
addictive but of course, any medicine should be researched for any harmful 
effects. I find it frustrating to hear how certain medicines can cause the 
very side effects it's suppoesd to treat!  Sorry I couldn't be more helpful 
with information but I can tell you it can help someone stay asleep and give 
oneself at least the 8 hours because it will leave you feeling sluggish for 
a little while until you eat something.  For more detailed instructions 
though please check the directions on the package and/or talk with a 
pharmacist.
