I've been on LDN since last June. Since then, my Crohn's has radically improved, but I have noticed heightened anxiety levels, especially lately. I never used to have full blown panic attacks until I started taking the LDN (excluding when I was extremely sick with my Crohn's, because, well, when you're really sick you tend to be anxious). Has anyone else experienced anxiety while taking LDN? Mine is getting to the point where I am thinking of asking my doctor if there is a different course of treatment that I can do for my Crohn's.
