HI Buty, I completed Chop-rituxan treatment last yr. And Praise the Lord am in remission now. The tiredness didnt last long for me. I just adjusted my routine to how I felt. Plus made sure I ate alot of protien. Found that drinking adirondyck flavored water. Was the only drink that didnt taste like metal. :) I now hjave maintenance rituxan treatment evry 6 months for 3 sessions I think. I may be able to have 4. But still have to check it out. Anyways my friend I pray youwill do well and regain your stregth very soon. God Bless Carla
