UGH! I have Insomnia

A couple of weeks ago I drank a Java Mocha Chiller from Sonic at about 9 pm. I didn't not fall asleep until sometime after 3 am only with the help of Tylenol PM. I thought it was just because I drank that coffee infused milkshake. Apparently not so! The rest of that week I did not sleep much and finally started sleeping again the following Saturday. All has been good until last night. I was so tired all day yesterday and thought I will sleep so good tonight. I went to bed at 9:30 and was just falling asleep when Audrey started hollering about One Tree Hill and startled me, then she came in my bed room twice looking for Rachael's shoes. Well, that woke James up from his 3- Tylenol PM Coma and he stated running in his sleep or wrestling King Kong. All I know is that he was shaking the bed and scarring me in the process. At 12:30 am, I got up and took my pillow to the couch. I finally sometime after 1 am got settled only after I went to pee. I didn't fall completely asleep for a while, then Perrie woke up at his usual 4:30 and let his dog out and he barked non-stop all over the holler chasing something. I was awake at 5:15 when James's alarm went off and I could hear him stirring. At 6 am when I knew he was done in the bedroom, I got up and went to bed. I actually fell right to sleep for all of 30 minutes when my alarm went off. I was not to happy needless to say. By the way, Perrie's dog was still barking...

If you have any cures, please let me know.
