Thanks, the homeopathic doctor I saw suggested a vitamin D deficiency and low levels of GABA may also be contributing to the mood disorder. Like I said I'm taking a handful of meds morning and night and am fearful of adding anything that may be harmful. My PDoc gave me the OK to take Chantix and needless to say I'm still smoking like a chimney...so I'm not sure she is 100% positive on interactions.
