Does Viibryd help insomnia?

Hi, Suzanne!
The side effects can go either way and they affect a small number of people starting an antidepressant:
Common (1% to 10% of users): Insomnia
Common (1% to 10%): Sedation, somnolence
Side effects generally resolve within days to a week or so and usually subside as the days go by. Ultimately, by relieving your anxiety and insomnia they should go away with continued use. Most people begin to feel significant improvement in the first couple of weeks but it may take 4-8 weeks to feel the full benefit of the medication.
Best regards and I hope you're feeling better quickly.
