So what are the side effects? Actually let alone LSD can reduce anxieties and depressions to migitate stutter, beforehands there are proven drugs like Risperidone or other substances that can migitate stutter but they are not universally effective in migitations and reductions, or even cures. So before LSD's researches about effectivenesses on stutter are published, you can't assure how much it can impact on stutter, or it's just another knowledge that I'm ignorant of. In addition, you mentioned above that thinking you are singing in speeches were all in vain. I think the root cause of it was that you hadn't entirely understand what this method is all about. First off you must practice singing to memorize subjectively the feelings and methods of 'making' sounds, and then divert these into your speeches, dubbed 'thinking singing in speaking', not just by imagining or assuming. I've introduced this method in my last post and I'm glad to see you can read this. I don't think LSD is not an expedient cuz you can't predict how long the effectivenesses tend to last for on stutters. Only after you alter you way of speaking to make usages of different brain areas, although I can't pindown them exactly, you can avoid abnormal areas that can induce activities to indulge your stutter more or less until entirely.
