I gave up on the B6 and the Niacinamide not long ago.  Nothing seemed to 
have happened, and I suspected the Niacinamide was making me more agitated, 
as if I wasn't agitated enough with all this OCD nonsense.  I did try the B6 
again at 100mg instead of 50mg, that didn't do anything either.  I am still 
intending to try B3 in the nicotinic acid form, as soon as I can get it.
