I’m doing it now. I did a ton of research on it and am currently trying it. I couldn’t find any of the 100mg Thiamine pills (they were sold out) so I use the 300mg and use a pill cutter to split them in half. I take one in the morning and one in the evening along with a magnesium citrate gummy (450mg). I do notice that when I take them it helps with my fluency, and when I stop my stutter gets more blocky and more regular occurring.
