Laz,

The Meyer's cocktail (magnesium, calcium, vits B5,B6,B12 and C)should help the fatigue normally associated with radiation and other then the Vitamin C/rads issue I can't see why there would be an issue. I say go for it as long as your RO is good with it.

Your DO I think is likely wanting to run up his billables this month on the testing. The CBC, CMP, Thyroid and Hormone panel I can agree with and encourage (not so close to tx however), the others I don't think you'll find much that you wouldn't already know about your body but then again being thorough isn't a bad thing.

Nutrition is an area most of our medical professionals know little about(http://www.nytimes.com/2010/09/16/health/16chen.html) nor focus on and after treatment it is very important to build the body back up. I think it's very intelligent to work with a nutritionist after cancer as well as your Dr to get a gauge of where you're at post treatment and devise a plan to get back to where you want to be.

Keep us posted Laz.

Eric
