I'm sorry your having trouble sleeping, no fun at all!!
My husband is gone for 5 days at a time, and I will have trouble sleeping sometimes the first day or so he is gone. If I am really tired and need to sleep, I will take 1 Tylenol PM and it helps me alot. If I take two of them, it takes me awhile the next day not to feel groggy, but 1 puts me to sleep and I don't feel that way at all. Best wishes on a good night's sleep tonight
