Good to hear you are taking cherry, are you taking tart cherry? Here is a good place to get LDN, your doctor may not be on board with this, and you might need to show them literature on it to them. If you are on FB I can steer you to some good groups dedicated to LDN and illness. LDN is compounded so your insurance may not cover it.
