"I have been taking vitamin B complex (specifically for the B6 and B12 that veggies on't get a lot of), ..."
B6 (pyridoxine) is involved in many aspects of macronutrient metabolism, neurotransmitter synthesis, histamine synthesis, hemoglobin synthesis and function, and gebe expression. It is a factor in the biosynthesis of five important neurotransmitters: serotoniin, dopamine, epinephrine, norepinephrine, and gamma-aminobutyric acid (GABA). The RDA is 1 – 3 mg/day. Doses of pyridoxine in excess of the RDA over long periods of time result in painful and ultimately irreversible neurological problems. There are 7 forms; Pyridoxine (most common), Pyridoxine 5'-phosphate, Pyridoxal, Pyridoxa 5'-phosphate, the metabolically active form (sold as 'P-5-P' vitamin supplement) Pyridoxamine (PM), Pyridoxamine 5'-phosphate (PMP) and 4-Pyridoxic acid (PA). Due to its half life of up to 25 days it is easy to buildup toxic amounts in the blood stream. Vitamin B6 toxicity is on the rise in the USA.

Fenugreek seed extract treats peripheral neuropathy in pyridoxine induced neuropathic mice. Our data showed that fenugreek has anti neuropathic effect and restores the function of nerve fibers
The German Commission E monograph recommends 6 grams per day, which can be taken all at once or divided between three meals. Since most fenugreek capsules are available in either 580 or 610 milligrams, a common dosing scheme would be 2-3 capsules three times a day.

We describe seven adults who had ataxia and severe sensory-nervous-system dysfunction after daily high-level pyridoxine (vitamin B6) consumption. Four were severely disabled; all improved after withdrawal. Weakness was not a feature of this condition, and the central nervous system was clinically spared. Although consumption of large doses of pyridoxine has gained wide public acceptance, this report indicates that it can cause sensory neuropathy or neuronopathy syndromes and that safe guidelines should be established for the use of this widely abused vitamin.

Half-Life is 15 to 24 days.

A newly recognised neurotoxic syndrome due to pyridoxine (B6) overdose is described. It is the largest series of B6 intoxication hitherto reported. A raised serum B6 level was present in 172 women of whom 60% had neurological symptoms, which disappeared when B6 was withdrawn and reappeared in 4 cases when B6 was restarted. The mean dose of B6 in the 103 women with neurological symptoms was 117 +/- 92 mgs, compared with 116.2 +/- 66 mgs in the control group. There was a significant difference (P less than 0.01) in the average duration of ingestion of B6 in the neurotoxic group of 2.9 +/- 1.9 years compared with 1.6 +/- 2.1 years in controls. The symptoms were paraesthesia, hyperaesthesia, bone pains, muscle weakness, numbness and fasciculation, most marked on the extremities and predominantly bilateral unless there was a history of previous trauma to the limb. These women were taking a lower dose of B6 than previously described (1,2), which may account for the complete recovery within 6 months of stopping B6.

Supplementation with pyridoxine at doses greater than 50 mg/d for extended duration may be harmful and should be discouraged.

"I know you must have been thinking this 'hat during your 9 months of it all. So much strength to have held thru it all."
Oh yea, for sure.
"Have there been cases before where other have been cross-tapering and still had the withdrawal such as those I am having, irrespective of the fact that I have a good dose of Citalopram going on?"
It is possible. In my case when i decided I had had enough the dr first put me on Lexapro which worked but I had a significant side effect; then Prozac which did absolutely nothing even though I was on it for 8 weeks and then the Zoloft. Other members have had similar experiences. I would estimate though that in around 80 to 90% of the cases the new AD works well.
Most drs like to adjust doses over a 4 or 5 week period. They know that going slower just extends the withdrawal out as you make drops in the Cymbalta. Get it over with, get on a significant dose of the new AD and hold on until it fully kicks in. BUT, just my opinion, your Citalopram should have taken a significant bite out of the symptoms by now. Unluckily there is no way to be sure if the citalopram is going to work out or not. I wish I could be of more help with this.
