Hi Christine - welcome to the forum. I just found KA about two months ago - I have had AS for 38 years. This site and especially the diet has given me more relief and hope than I have had in many years.
Please spend some time and read as much as you can.

Yes when I started the diet I was fatigued and week - but that passed in a few days. The diet helped me in 3 days
