Yes, thank you. I have discontinued the 50 mg of B6 last week and yet all last night from 11 last night until 11 this morning I was having severe muscle tetany. I finally went to bed about 8 this morning and had a semi-conscious sleep for 3 hours as I continue to work through the muscle tetany trying to stretch it out but nothing worked at all. So it is coming from another source than the B6. I am not a happy gal needless to say we'll get through this as I always do. This is not a rare or isolated incident. It happens far too often. Thank you for sharing, Sunny flower
