Follicular lie grade Lymphoma stage 4

Hi. I was diagnosed with advanced follicular lymphoma in 2017 and had 8 sessions of chemotherapy. I was told I had good results following the chemo. After chemo I was put on  a 2year maintenance programme of Retuximab (an injection every 8 weeks) and kept pretty well throughout although experienced sore joints, fatuguie, flat moods and low grade infections from time to time. 
I have now   just finished the 2year Retuximab treatment which should prevent the Lymphoma from returning for up to three times longer than  if I hadn't had the Retuximab. I'm  wondering what I can expect to feel health wise going forward and would appreciate hearing from people who have had a similar experience.  Thank you
