Anti-MAG fatigue for newly diagnosed.

Hi All,  I can see these forums aren’t used much.  I’m not sure why because I’m chomping at the bit for more information.  I’ve recently been diagnosed with Anti-MAG with just over 1000 BTU and no M-spike/MGUS (yet).  Neuropathy began about thirteen years ago, but symptoms have very recently gotten much worse.  The sensations of weakness and parasthesias are increasing.  For those who have had Anti-MAG longer, may I ask you how bad your fatigue got?  I’m currently needing at least a two hour nap nearly every day.  I work out hard in the morning and then hit the wall.  Also, did the rituximab help with fatigue?  Lastly, did any of you try rituximab, but didn’t find it working to improve symptoms?  Many thanks in advance.  Best wishes, Karen
