Chemo/radiation treatment for anal cancer

I have been diagnosed with anal cancer and start treatment this weekend. I will have 6 weeks of radiation therapy, 5 days a week, plus chemo therapy using Mitomycin and Fluorouracil. The Fluorouracil will be given via a PICC line for 4 days, then again 4 weeks later, again for 4 days. Has anyone had this treatment for anal cancer? If so, how were the side-effects? I've had the cancer side effects education session, so have a good idea of what to expect, but just wondering if anyone could share a 1st hand experience. Thanks in advance!
