@parrotqueen thanks for the tip, I would like to try it. I just had back fusion on my lumbar and I think after 3 1/2 weeks that it is going to be successful. I am very hopeful, but I also have a lot of arthritis pain particularly in my hands. I also overdid the nsaids and I can’t take them anymore. Can you tell me do you buy yours at a health food store or over the Internet? Does it cause you any stomach indigestion? I find taking calcium and some vitamins really upset my stomach.
