I had double dose chemo too, Adriamycin and another one (can't remember the name right now). I was constipated too and went to the doc to make sure rectal bleeding was related to that only (didn't need any more problems that's for sure). Doc told me to take stool softeners two nights before the chemo treatment and then afterwards until stool became softer. Also, drink ALOT of water. I mean ALOT. I still do this (I'm still in treatment). Take water to the treatment w/ you and drink it. Also chamomile tea helped too. I hope this helps you - I completely understand what you're going through. Don't give up, take it day by day, that's what I'm trying to do too!
