No, I haven't ever been that anemic. A friend of mine had to have the infusions last winter. She was pretty chipper afterwards - she said that she didn't realize exactly how tired she had been feeling until after she had the iron infusions and they took effect.

I didn't know that you had lupus - bummer.

I linked below to some info. on side effects. It says possible nausea but doesn't specifically say vomiting. I'll bet they'll be able to tell you more when you get the infusion done. I hope it helps. The info. I looked at said noticeable results in one week to a month.
