Enna,
I found an LDN forum on a Crohn's disease site which has lots of info. pertinent to all users of LDN.
It seems there are many variables involved in achieving success with LDN.
If you have disturbed sleep it was suggested that you lower the dose you are taking. Others suggest you take your dose 4 hours earlier than you have been taking it. The following link is from another board with different ideas about taking LDN earlier.

People commented that the filler used by the pharmacy caused issues. A few people said they were given slow release, not the fast release LDN required.
Other people commented that they were given old LDN which was not efficacious. Stale pills. Some people found that when they switched providers of LDN they had a remarkable improvement.
One poster named Kev successfully took LDN from 2006-2014, but lost his remission, in his case there were lots of factors which could have contributed to his negative outcome, while another poster said that after taking LDN he was completely cured.
