I've been on LDN for a year. It put me back in remission after a year of ups and downs. about 2-3 weeks after taking it I was about 80% better. Then I started a gluten-free diet, and was 100% better. I am grateful for it.
I occasionally have an unexpected or loose BM, but true diarrhea has been very rare for me since LDN. Well of course tonight I had the first watery stool in a year so I'm freaking. Hopefully it's just stress-related and not a true flare, because I would hate to see teh LDN effect end.
Anyway, i encourage people to learn about it, and consider it.
