Should I Increase The Dose Of Methadone And Recently Tried Increased Kratom With Minimal Effect?

hi, I m on 40 mgs. methadone a day and recently tried 3 grams kratom divided in two doses about five hours apart. I tried to hold off on the methadone to see any potential effect. I thought my pain subsided( maybe it was all in my head ) Dr. please shed some light on my experience. It s only the third day using kratom. Should I increase my dose? My friend used 12 grams first time and said he experienced a little energy and even exercised a bit but he still had pain. Please shed some light on what I ve said here and please make any recommendations, for I am very interested in kratom even though it has not been researched and or FDA approved. Thanks
