It took a few nights for me to get used to the pillow. The first two mornings I woke up with a pain in my neck. The third morning I woke up without the pain. I was hoping to find the perfect pillow and unfortunately, I still don't think I have. I sleep on my side for the most part, and I don't think this pillow is made for that. My husband absolutely hated his and I had to replace his with his old one for him to sleep. I will need to keep looking for the perfect pillows.
