Results will vary. Psilocybin does wonders for treating my PTSD, but my stutter and stammering are still triggered by certain people or circumstances. (Mine started after enduring severe trauma and violence.) Do your research. I've microdosed for 6+ years, 0.1 - 0.2 grams (135lbs female) primarily Golden Teachers or B+. These days I rarely need more than a dose a month, which I take right before bed because sometimes it can make me a little nauseous or anxious feeling. If you're planning to dive in head first and really trip, do not do more than 1 gram your first time and stay away from the potent strains. I highly recommended Golden Teachers. Have your environment extremely safe and soothing. Bad trips happen, and it could cause more harm than help if things get out of hand. Like result in physical and/or mental injury, and potentially make your stutter worse. This wasn't even a trip, but I microdosed once on some very potent Penis Envy and went a month unable to stand being touched by anyone, crowds were impossible, and my stutter was worse for at least 2 months. That's why I say results will vary. This is just my experience, but I hope it helps and you find something that improves your life.
