I am also taking LDN 3 mg. My doc started me at 3 and won't increase me "because of my weight". I am 5'4"and 111 lbs.
What problems did you notice when increasing from 3 to 4.5? I don't know if LDN is helping/hurting my leg stiffness. There has been no improvement there. I do sleep better, have vivid dreams and a better feeling of well being, more energy and less trips to the bathroom!
Glad your insurance is helping you pay,
