Sure : ) - try what works !!! We are all different and one never knows what could be a "lucky charm" ! My CRS suggested using both alternatively LOL - I had no side effects !

I think that now that your fissure is healing nicely and you manage your poop consistency that you will heal in no time anyway : ) !!!
Best of luck !!!
