Anne, Gary is right on the money all the way down. I used Ativan for anxiety and still do, and Percocet/Oxycodone for pain. And I was gobbling those guys like candy during treatment. For the last 2 weeks of same I had a 25 mcg Fentanyl patch to help. I was still in pain, but the Fentanyl I think smoothed things out.
Ditto Diflucan and Zofran. I found the latter didn't really help and it wasn't until I discovered good old Compazine several months after RT ended that I got some relief from 24 hour a day nausea. And I didn't have chemo, so the nausea was caused by the radiation alone. I hadn't expected that. My doc also put me on Prilosec right off the bat as she anticipated gastric issues, and she was right.
The constipation issue is a real bummer. (sorry.... couldn't resist) Something to be taken very seriously where long term opiate use is involved.
I may have mentioned in an earlier post that the best stuff I found for my skin when the burns got bad near the end was Silver Sulfadiazine cream. It's another old-line med, like Compazine, and it's great. You'll also probably get a topical like Miaderm for everyday use.
It's great that we have all these wonderful chemicals to help us out. They really do!
Best.
