I'm glad you're doing so much better, but I think the clinic that said since there is no "cure" it means you would be taking the meds "forever" are seriously out of line.
They have no way of knowing that, and for many people the symptoms will eventually lift.
That was my experience, for example, some forty years ago with Chronic Fatigue Syndrome, which felt the same as my present (1-1/2 year) bout with LC, and went away of its own accord after two years.

As far as this thread goes, and this has already been previously discussed multiple times--use the handy search tool, folks--I did try the LDN starting at a .5mg dose, going up to ten times that over a couple of months, and felt no effect for my ongoing fatigue/PEM.
