Generally speaking I agree it's best not to take 20 grams, especially first timers. But if you have taken smaller to medium doses multiple times and are comfortable and familiar with the effects. I think you should be safe. I ate a half oz not long ago(14 grams weighed) While it was quite the experience I don't believe it affected my stutter. I have stuttered my whole life, 40 years. I'm pretty comfortable with it, as is everyone in my life. But yeah, I do totally agree with all what u said. Especially how they aren't the cure, but can show u what u need to know.
