Caffeine and stuttering

Caffeine and stuttering Is anyone’s stuttering greatly affected by caffeine. When I go from no coffee to drinking coffee I am initially pretty fluent but then over a few weeks period when my body builds a tolerance to it I become very severe. Then I quit and it takes a few weeks for my speech to go back to normal. The problem I have is I am addicted to coffee and find it extremely hard to quit 😂.
