when i was describing to my compounding pharmaicst (who makes my LDN) how LDN helps me (heals up inflammation much faster than without it, heals up tendon / ligament tears / pulls much faster than without it), he said that's the way many of his RA customers describe it as well.

i could tell you a number of stories at this point that would illustrate how much faster; i have 11 years prior to LDN to compare to, and have been on LDN a bit over a year now.
hmmm? getting sick? i typically get a head cold once or twice a year, haven't had one yet on the LDN, but we'll see if i get one this winter before we judge. i never really got sick (infection wise) much before LDN, so it will take some time to decide if the LDN is affecting that area or not.
