I was working with anIntegrated Medicine doctor who was a big believer of LDN and I took it for a couple of years (I can't remember the dose) to treat my chronic sinus infections and asthma. I didn't have any side effects, but I'm not sure I noticed any real improvement either. I too, would love to hear others' experiences and wonder if I should start on it again. The doctor left the practice, so he wasn't around to order the prescription anymore, which is why I stopped using it.
