i was the same when i did mdma. i felt the come up anxiety which made my speech worse but soon as it hit me it was like a light switch had been flicked. i wouldn’t shut up lol, i wasn’t stuttering either. that lasted about 6-7 hours before it started to wear off, and that’s when my stutter came back. i got kinda sad when i realised i was stuttering again hahaha i loved the fluency. it’s now been about 18 months since i touched mdma, no other substance has done that for me. i smoke weed, and that relaxes me which in return reduces my stutter slightly. it’s weird how different substances can have such drastic effects
