I managed to get off the energy drinks a couple months ago and I had a can of monster in work the other day and it made me so much better Maybe keep note of the caffeine your having a day to see if there’s a pattern I also have days like this where I could be fine all day and then it’s down hill from there. For me, I think it’s just the anxiety around stuttering so once I’ve had a bad stutter, I’m really cautious of it happening again
