I need sleep!

For the past few weeks I have been having a hard time sleeping. These past few nights it due to coughing thanks to the cold I have but when I don't have the cold its like I can't sleep. I have tried to stay away from using the powerful drugs to help me sleep but I want to just get more than 5 hours of sleep too. Today while looking online I found a site of where I could get a natural sleep aid. That might help me be able to sleep on the nights that I am unable to and also for when I need the extra help I know I won't be putting anything harmful into my body either.
