The only reason B6 is in those carbs you consumed, is to give them "some" nutritional value (which is minute IMO). Often empty food or food with highly refined flour has some small fortification added, to make people think it is "good for you".

It is insignificant when considering B6 toxicity which is pretty uncommon and only occurs when over 100mg is consumed daily for long periods of time. Some doctors, use the upper limit of 200mg a day of B6.

I don't think there is a reason to use more than 50mg a day for most people and situations.

This is good, that you are weaning off the clonazepam. In your first posts you said you were taking 1mg twice a day.

Klonopin comes in disintegrating tablets that start at .125mg and up. This should help you wean off more comfortably when that time comes.

Klonopin became very heavily used when Valium's patent expired. Many became very habituated to it, and I've read it can take 6mos or longer for a taper completely off.

Elavil is not toxic in the small doses used for PN. It can work at 10-25mg a night. There are some anticholingeric side effects, which males with prostate issues might not be able to tolerate.
Elavil (amitriptyline and its active metabolite nortriptyline) are the only antidepressant (TCA type) that have shown some use in stimulating nerve growth factors. Hence, helpful for damaged nerves.
