Is there anyone else out there who is on the REACCT trial

I was diagnoised with b.c. last July and had a masectomy last September.I have been on Tamoxifan and this Trial drug for nearly 6 months now.I feel terrible most days but keep taking it as i dont know what else to do for a bit of hope.I have also lost so much weight in my face that it is really worrying me.My breast care nurse said it was because the chemo had stopped.Is there anyone else feeling the same?Looking forward to hearing from anyone.Regards Gill
