insomnia
"Ambien has been a lifesaver for me.  I have had insomnia since I was a teen, and Ambien has been the only medication I have used that works for me.

There are plenty of "strange" things that can happen if you try to do things between the time you take the medication and onset.  

IMPORTANT:  If you are going to take Ambien, be IN BED, ready to sleep.  It takes effect VERY quickly.

Great medication for insomnia!"
