Magnesium and Thiamin

Magnesium and Thiamin Hi, having success for my stutter with good quality magnesium and vitamin c (vitamin c helps the magnesium absorb). Can say my name easily now.. had a great 2 years but recently I've been blocking more on certain syllables. Still I'm more fluent than I was before magnesium/vit c. Heard recently about Thiamin.. anyone tried it? Gonna give it a go. Any other supplements that have worked for you guys?
