I have been studying the web for awhile about tardive dyskinesia, because I am now 63 (older woman and therefore at greater risk) and have been taking typical antipsychotics for 38 years.
Has anyone else read the good reports on taking megadoses of Vitamin B6? The studies give absolutely no hint that overdoses are a problem. They are!
If you are reading the web as I am, and getting advice about megadoses of vitamins, check "vitamin x overdose" on the web. The studies are usually very short-term, and the results of long-term megadoses are sobering.
