I have suffered from insomnia for a few years now. I've been prescribed to many medicines over the past few years and have tried the teas, melatonin, etc. Nothing works at all. I had just been prescribed to a new medicine when I found out I was pregnant so  had to stop taking it. My doctor gave me a list of medicines and for insomnia said unisom was okay. I've taken it a couple times and it helped a little but I'm just scared to take it all the time. Is anyone else taking anything or have anything to recommend? I'm literally exhausted by the end of the day and have no energy at all!
