Just saw your question, Linda. Sorry to take so long replying. I did try infusion therapy, with mixed results. I had what's called a Myers Cocktail, which contains vitamin C, B vitamins, and magnesium. The only thing I noticed was increased energy the first few times, but I was already feeling much better when I started the infusions. (I started them after a terrible flare up of inflammation, thinking this might prevent it from happening again.) The last time I had an infusion (I had 5 altogether), my blood pressure shot way up, so I decided to stop them. They're also very expensive -- $250 each.
