Those of you that do IVIG.. do yall feel more weak the night of the IVIG and the next day before feeling better?? My ivig was wearing off this past week, but I got another round of IVIG today and I feel more weak tonight (granted I'm sure the benadryl they give me doesnt' help any either)... Last round, I felt bad and weak, and then 4 days after the IVIG felt like superwoman for about two weeks! it was pretty amazing.. anyhow I was just curious if anyone else feels this way?
