I can tell you the B Vitamins are working for me! Depression, GAD, and now PN. Effexor XR, Zyrtec, both current but Effexor down to 9.3 mgs as I'm weaning off. I took Gabapentin for approximately 6 months, became suicidally depressed and stopped taking it when I finally figured out that the Gabapentin was the problem.

Since starting the B vitamins and especially the B-12 I have no more fatigue like I used to have: Most days couldn't get through without a nap. No energy, no ambition, nothing. Some other symptoms that I believe may have been caused by a lack of B-12 are also abating. I've been taking the B Vitamins for 30 or 31 days now.

Other than this I'm just beginning to start on some research of natural supplements, herbs and other things that might be causing some of my problems because of a deficiency.
