Hi! I have been on it since July. I’m not having any side effects, thank goodness! My tumors have shrank a lot and my markers are down! I also drastically changed my diet. I’m doing about 90% vegan/raw and I drink 64oz of juice per day. I’m thinking that maybe that why I don’t have the diarrhea. When I do eat something not so great I do get it though. I also take a supplement to help keep my immune system up. I found it in a group on fb, another lady took and said her white count was never low even through chemo! Good luck. Also, I take the Letrozole at night due to hearing people getting achy bones from it.
