Insomnia please help!!

I found out i was pregnant 2 days ago, being 5 weeks in. I suffer from insomnia, can this affect the baby? The lack of rest i rest i mean. I assume it will. However, what im looking for is a natural alternative to make me sleep adecuate at night. I used to take nyquil and stuffs like that to "relax" myself during the night, but i dont want to take something that could harm the baby.
