... some side affects. I've been having a lot of charlie horses, my face has been breaking out, a little moody, etc. My biggest concern is that I am 50 and was perimenopausal. Have not had my period since taking tomaxafin but for the past 3 plus weeks have abdominal cramping like period daily on and off. I know this drug can make changes in this area but this soon. With being on the edge of menopause, etc. I don't want to call my doctor for every little thing. I have an appointment in a month with my oncologist and plan to discuss. Just wanted to know if any of you have experienced this and what was the discussions, etc. with doctor. Do you think I should wait until october. It's not that far away
