Dr. Sonya L Merrill has the following 2 specialties

  • Sleep Medicine

    A sleep medicine specialist is specially trained in diagnosing and treating disorders involving sleep.
    Sleep disorders such as sleep apnea, restless leg syndrome and insomnia are very common and can often cause other serious health issues, such as depression, asthma, and migraines. Sleep medicine specialists often work in sleep centers where they observe a patient while sleeping and monitor brain waves, behavior, and vital signs in order to identify the causes of sleep disturbance, or an inability to sleep (insomnia).
    Sleep medicine specialists treat patients through advising on sleep hygiene, providing cognitive behavioral therapy, using light therapy, or medical sleep aides.

  • Internal Medicine

    An internist is a physician who focuses on the diagnosis and treatment of conditions that affect the adult population—both acute and chronic.
    These doctors are often who adults see as their primary physicians because they treat a broad range of illnesses that do not require surgical or specialist interventions. They also work to help a patient maintain optimal health in order to prevent the onset of disease.
    In addition to treating the common cold and flu, internists also treat chronic diseases like diabetes and heart disease.

She found a long sought after solution for me.

I have been to 5 previous doctors specializing in sleep. I had insomnia, sleep apnea and had no success in getting the answers to my problems. I have serious heart problems and sleep is essential in keeping anyone well, but is especially serious for me. She was very pleasant, goes over all your medical history, adjusted medication to help me over my issues and told me all the side affects and pros and cons of each one. She was very careful not to prescribe me anything to cause me more problems with my health problems. She did not give up on me and knew I had a tough time using the CPAP and masks. It was her caring, concern and experience that helped me find a solution. At times, I still have insomnia and problems sleeping, but I'm 90% improved from where I was before I walked through her door. She's highly regarded by other physicians and they send their most difficult patients to her because they know they can trust her to find the best solution. Unlike the negative review I read, I found that my experience with Dr. Merrill to be one of the most pleasant and beneficial visits to a doctor in my 63 years.

Worth the 4 month wait to get in!

I am VERY impressed with Dr. Merrill. Her schedule runs on time and she is very thorough. She has a great bedside manner and seems to genuinely care. She talked about the latest studies in sleep medicine vs. past beliefs, so she stays current in her specialty. Most of her recommendations were common sense: bedroom is for sleeping, not for watching tv etc., no stimulating activity before bed, no caffeine after lunch, go to bed and wake up with as much regularity as possible, etc. She gave me my choice of sleeping medications to try first, talking about the pros and cons of each. Her follow-up was excellent and she made adjustments to my medications until we found what works for me. Her schedule stays booked for 4 months, or more, but she is worth the wait.

I recommend Dr. Merrill

A friend of mine who has apnea gave me her information. I have insomnia.I think she is very caring and concerned for my well being. I dont understand the negative review provided. She has already helped me a great deal.It is difficult to get a quick confirmed appointment. However she does have a waiting list. The office person was very patient with me when she would call and offer me a spot I couldnt take due to my travel schedule.I would highly recommend her. I want my husband to follow up with her on his apnea as well. He saw a different sleep Dr.
