natops- glad you felt some effect from it, but sorry it didn't last long!
Was this your first round of IVIG?
I had my initial loading dose in the hospital and only had mild improvement.. I was defintely better, but it was mild enough that I wondered if it was just placebo effect.. it wasn't until the 2nd round that on the 3rd day or so afterwards I woke up a changed person - like my old self! it lasted about 10 days until I felt it all start taking over me again..
The neuros said a lot of people take a few rounds before noticing a difference .. have they talked about DAP as well ? I hear the combo of IVIG and DAP is what really works for LEMS..
Do you have facial symptoms? ptosis and swallowing/speech issues at all?
Good luck!!!
