I have been having a lot of trouble with my neck where it got to a point I couldn't turn  my head to the left without considerable pain. My neck would ache all day long. If I did exercises that stretched the neck out- it would help but not last. Sleeping was worse and I always woke with the most pain. A cousin of mine was having neck pain and posted on Facebook if anyone had any suggestions to help her. Someone thank heavens wrote in and talked about this pillow. I decided to try it. What a blessing. The first night I only woke up a couple of times. In the morning I could move my neck with only a fraction of the pain I had before. I had no problems adjusting to this pillow. I have been using it for almost a month now and will not give it up. I won't say it cured me, but the pain is very tolerable now and I am able to move my neck so much better. I am extremely pleased with the results so far and am getting one for my husband.
