This stuff is nothing to play with... Have been on it quite a while now, had it today and am VERY tired, exhausted, one might say... It's great after Chemo ( with the Platinum Drugs) and Radiation , but the side effects will need to be monitored... I'm glad to have found this site, because I have NSCLC, Pancreas and Bladder Cancer, and I was basically at my Wit's End... Truly...
