Thank you, Justin. The first treatment was divided for two six hour infusions. There was no serious reaction, but I had side effects that included extreme muscle, joint and bone pain. With doctor permission, I took daily Claritin and it reduced that pain problem by about 90%. Other side effects have been loss of appetite, feelinh "ill", and significant physical fatigue. There seems to be little rhyme or reason to a pattern, but mental energy is consistently good. So to give positive meaning to the eight weeks, I completed printing three books for my family instead of pitching them to publishers! (Always a long process.) To give positive meaning to the eight biweekly treatments, I am writing part B of the second children's book. This treatment is not a walk in the park, but allows for meaningful living, and reconnected me with old friends fron my writers group! And it is successful in lowering my kappa free light chain. I am hoping others may report they have found more energy as time goes on.
