jazzydude, I've been receiving Vitamin B shots and the Myer's Cocktail intravenously for approximately two months, and have also been taking a number of additional supplements (B, C, Zinc, Iron, ALA) during the same period.
I have yet to experience an improvement in my symptoms, but recently had another blood test to determine whether the injections/IV/supplements etc. are actually having a positive effect on my results.
Obviously, this is just my experience - you may be more successful.
