Response to residual effects from IVIG

This is my first post. I have been having loose bowels since using the gabapentin (neurontin). This has been happening since before I had the IVIG for CIDP. Does is anyone suffering from bad (but not migrane headaches). Also, a friend of mine keeps saying that she has found articles condoning the use of marijuana for the pain associated with CIDP. Unfortunately, I never seem to be able to access these articles. Anybody know? Also has anyone experienced severe irratability from IVIG or did I just get immonuglobin from crabby people? Kidding about crabby people but not about the irritability.
