I too had a bout with B-6 overdose
when ingesting 200-300 mg/day for a mild case of carpal tunnel. My symptoms were not as serious as others mention
ed here since I was on
them for less than 2 weeks, but it was scary and did mess with my thyroid, heart, intestines, and I had vertigo in addition
to numbess, pain and tingling. I think I was toxic this quickly due to some kidney impairment. Anyways, I am very glad to hear other sufferers are recovering.
