what medication was most effective at stopping your stutter?

what medication was most effective at stopping your stutter? I have a few social events coming up like job interview and wedding that are giving me bad anxiety because it's natural for me to get like this when I'm in a situation where I might stutter badly and get publicity disresped. It's a reaction that's very hard to change. I'm currently trying phenibut twice per week at 300 mgs, this last week it didn't do anything special for my speech. I feel like I need a med that mostly elimates anxiety & raises my dopamine do a certain degree. I've tried lorazepam & Lexapro which actually made my seratonin too high & I stuttered worse & made my mental state really bad. I've also tried Kratom which is OK but just made me feel out of it and sluggish, not mentally sharp enough for social interaction. So let me know what meds you tried that was most beneficial for anti anxiety & social fluency so I can ask my doc for a prescription. Thanks!
