Day 1 ————————————————— amount of B1 (mg/day): 200 amount of magnesium (mg/day): 0 speech (1 worst - 10 best): 6 speaking situations (1no situation - 10 a huge amount of situations): 6 well-being (1 - 10): 6 (i have a cold) short summary about the day: First half-day with B1. I had any situations in my job, and my speech was not bad. At the evening, i talked with my mom almost fluently (10 minutes). I don‘t think, that this are already impacts from the b1, because i took the first capsule a few hours ago. Maybe I start in a ‚good speaking’ phase.
