I recently was able to become more fluent through a few tricks. One of the things isn't really a trick, but I was out of gabapentin for 5 days and it reduced my stutter being off of it. So I talked to.my psych and she said it was okay to go off of it. I don't recommend going off your meds on purpose without a doctor's consent, but it may be worth if you're on meds to look into if any of them can contribute so slow speech. The other tricks are practical, firstly slow down. There's no need to attempt to be the quickest whit in the room. If the people you're around know you have an issue, they should be willing to let you say what you have to say at the pace you're comfortable saying it. Next, try to speak on an exhale. If you feel a stumble beginning, stop, take a deep breath, and speak the words on the exhale. Third one is a little hard, but very helpful, don't go into a sentence expecting to stutter. If you're expecting to stutter you almost certainly will. If you speak with confidence in the idea that you will be fluent, it's easier to manage it through maintaining a comfortable pace and speaking on a breath.
