I tried LDN c.6 years ago, before I got LC, and was probably still taking it into LC since I had numerous chronic diseases then said to benefit from it, including fibromyalgia but though I slowly titrated to full dose didn’t obviously get any better. I might well give it another go! I have tried to do a one drug/ supplement change at a time … it’s so slow going it’s quite easy to spend 2 years getting back to where you were, as I am with antihypertensives… I have to try to think which drug is responsible for making me more breathless, reduces BP but increases HR, and which is preferable as my medics not very concerned ( in Uk)…
