hi tantija.
i was diagnosed with crohn's in early 2010, and after having little success with conventional IBD medications, i decided to try the SCD 11 months ago. although i've experienced some ups and downs (which "breaking the vicious cycle" prepares you for), i am seeing significant improvement in my condition. i have practically no abdominal cramping, hardly experience diarrhea anymore, have a lot more energy, and feel that i am thinking clearly again. this obviously is not an easy diet to follow, and requires a significant change in lifestyle (i cook way more than i ever used to), but i'd say it's definitely worth it - it has changed my life dramatically! you may also want to check out the GAPS diet, which is based on the SCD, but eliminates dairy for those who are more intolerant of lactose.
good luck with it, and let me know if you want any tips on getting started and keeping up the diet!
