I won't kid you it wasn't easy breaking 60 years of sleeping on my right side but the system worked and now that I have the routine down I wake up with no pain whatsoever. Most noticeable is no sharp pain, getting out of the system in the morning, the biggest problem I had with the system. Pulling my arm and shoulder out of the confined pillows started the day off with a sharp pain. Now, since my problem arm and shoulder never bear any weight while sleeping, morning pain is now gone. I am a satisfied, happy customer. A whole lot better and cheaper than the shoulder replacement surgery the orthopedist recommends
