Hi Adriana!
Yes, I am currently on the GAPS diet after doing research on it since August 2011. After some issues with reactions to different meds and now not being able to afford Entocort and it's hefty $1080/month price tag, I am toying with the idea of using Gaps strictly to see if it actually will help my body heal.
I am breastfeeding an almost 7 month old, so I am just doing the Full GAPS diet and did not do the Intro or any of the stages as I didn't want to detox and pass toxins in through my breast milk while detoxing. I have been on it for 2 weeks, and although it is early, I am feeling well. I am slowly increasing my probiotics and fermented foods, which little reaction, but I already was eating in the Nourishing Traditions style before.
I'm definitely no expert, but if you have any questions about this diet, feel free to message me. I do believe that eating this way can aid your body in healing. I'm not convinced that I can be "Healed for life" but I do believe that you can take appropriate steps in aiding your body.
Best of luck to you!
