Sleep Deprived

Ever since hubby got home...I've encountered a problem...I can't sleep. I mean, I sleep but I never rest. I go to bed tired; I wake up tired! Anytime during the night I can wake up wide awake. The other night when I thought I was asleep (and evidently hubby wasn't) he told me the next day, all I do is toss & turn - the whole time! I'm not sure what my problem is. Is it because I'm not used to him being back in the bed with me or do I really have trouble going to sleep & resting? This past weekend, I was able to sleep in which is a great feeling, but it still happened & I woke up with a tension headache because of clenching my teeth so tightly (probably because I'm so tired & stressed that I'm not resting). So, tonight I am trying a Tylenol PM to see if that will help & I have an extra hour to sleep due to the prediction of snow in the area...so we shall see. I'm so tired of being tired. I want to just rest peacefully. Well, I'm off to hopefully catch some zzzz's! Have a good night!
