Allen, I don't take IVIG -- but, from what I've learned from members in another group -- your body gets used to one brand. Don't let them change brands on you again IF this one agrees with you. Gammunex is supposed to be the "Gold Standard", so stick with it if your body likes it.

Also, 10 weeks between treatments, from what I have been told, is TOO long. That is probably WHY you feel fatigued. It is like using pain meds after surgery. You want to take them BEFORE you start feeling pain. You want to take the NEXT dose of IVIG before the FIRST dose wears off. I'm thinking every SIX weeks -- but, you "might" be able to go EIGHT weeks.

Also, remember to DRINK, DRINK, DRINK!! This is a medical procedure -- and you need to treat it as such -- don't push too much!! You'll probably be "good to go" by Monday.
