I cannot fall asleep?!?!

I cannot fall asleep?!?

It is after 3 am & I am wide awake. I have been staying up till around this time tossing & turning every night. Once I do fall asleep, I'm fine- so I don't think that I have insomnia. Any ideas on what to do? Also, I am trying to concieve so I don't want to rely on Tylenol PM.

I've been staying up more often since summer has started. Do you take a lot of naps during the day or something? this would effect your sleep schedule. the thing that works best for me is to exercise at some point in the evening. this way your are fatiqued at night time but yet not so tired in the middle of the day you end up taking a nap.
