When I know I need to present I use a technique my therapist helped me with. I break it down into chunks. For example, If I was to break down your post, I would write on paper something like this: I have a presentation to give | tomorrow and am | starting to get anxious. I was just wondering if | anyone had any tips that they use | to reduce stuttering | during a presentation. Where you break the sentences up will be different than each person, just practice beforehand and any point where you struggle or feel you need to slow down, pause and take a breath there. It helped me an awful lot. EDIT: I know I am a bit late, but I still think it can help.
