TTW and insomnia

Tiffany
Does anyone know of any herbal remedies to help with insomnia. I'm basically trying to eliminate anything I can't have while pregnant from diet especially during my TWW. I don't want anything to jeopardize my chances of getting pregnant. With that being said I haven't slept in 3 days. I've suffered from it in the past but normally I just take a sleep aid and it will get me back on track after a day or two. I'm working on getting new insurance so I can go to the doctor as we speak but I don't know when that will kick in. Any help would be appreciated!
