Day 4 (Monday) ————————————————— amount of B1 (mg/day): 300 amount of magnesium (mg/day): 0 speech (1 worst - 10 best): 4 speaking situations (1no situation - 10 a huge amount of situations): 6 well-being (1 - 10): 7 short summary about the day: I spoke a few hours with my grandma. Every time I am speaking with her, I am stuttering really bad, but i like it to speak with her. Also today i stuttered a lot, so vitamin b doesn’t show an effect until now. Later I was at a poker evening in my company. There I spoke nearly fluently. I think the reason is, that I only thought on the game, and I had fun with bluffing. I also ordered thiamin hcl and magnesium, and I will switch to this next week. I hope this will works better.
