Imsomnia! Help!

6 months and a week. And for the about the last 8 weeks, i have really bad insomnia. Maybe I will take a nap during the day while my 5 year old is in school, but then at night, can't sleep! And then by the time I would like to go to sleep, my husband's loud snoring keeps me up. Most times I won't fall out until 4am and on the sofa. Some nights I have to Tylenol PM. What can I do???
