Welcome back Karen, nice to hear from you.
I'm so sorry that LDN doesn't seem to be doing the job for you. I don't blame you for questioning it's efficacy for you.
Are you feeling any benefit at all? For instance, I don't notice walking any better, but I do notice better urinary and bowel control. I have also noticed that my fatigue level is just normal and not horrible, as it was, prior to LDN. I also notice an overall feeling of well being (most days).
I've been on it since April 12, 2003 and I know it's still helping me, but it is not a cure...Once I came to terms with that, I'm ok with it.
I will pray that LDN keeps the MS Attack Rats and Progression Rats away from your door.....any extra benefits would also be nice.
