My father had Ankylosing Spondylitis (AS) many years ago and suffered for 2 years. He and my mom began a vegan antiinflammatory diet and within several months he was cured but it took way too long. Well when I began exhibiting similar symptoms a few months ago I knew right away what was happening. I was getting excruciating pain at night and my back would stiffen up. But once I got up and went about my day, the pain would greatly subside...only to return again the following night. Well then I began my search for a fast cure. I came across the no starch diet, which reportedly works really well for many with AS but I love potatoes and wasn't ready to give them up just yet. But then I came across a couple testimonials of people using apple cider vinegar. I happened to have some so I began drinking it during the day at work.
I kept a large 1.5 L bottle of water at work and I would add about two or three tablespoons of ACV in it. I would drink it throughout the day. Well I noticed almost immediately that my symptoms subsided. I was still getting discomfort at night but nothing like before. The improvement was about 70%.
On the days I would forget to drink the ACV, the pain returned with a vengeance at night. One night before going to bed u panicked because I realized I had forgotten to drink the ACV earlier. I panicked and grabbed a tall glass of water with ACV in it and just chugged it down before going to sleep. That night I had zero pain. I realized that the key was to drink it within 20 minutes of going to sleep. I now sleep painlessly! It's a miracle. I use organic acv.
I hope this helps someone.
