Hi all.... It’s only my 4th day on Imbruvica. So far, I’m feeling well. Few short episodes of queasy stomach but nothing serious. Staying well hydrated. What I am experiencing are muscle cramps in my legs. For those of you who have experienced this, what has your specialist suggested or what have you yourself done to help the matter? My wife takes magnesium 500 mg every night but I don’t want to start adding any supplements without consulting with my Oncologist. Looking for some tips, thank you.
