I'm certainly not an expert but do know about the B12 issue. I've been working with alternatives for my own health for over 25 yrs and have had my share and others share of side effects and damage from so many drugs. I'm a huge believer that so much of our issues can be worked with or managed alternatively.

For me, I have gotten a "cure" for allergy/sinus issues I had for a lifetime prior to 1995 when I found pycnogenol and then grape seed ex which are OPC's and address SO MANY health issues.

Integrative MD's work firstly with supps/vits/minerals etc and if and when needed will go to the pharma drugs.

I see you don't have insurance...I use Google for health issues I want to work on. I don't run to the doctors.
