The last week, I had three presentations too, I’m in college and the last week were the final projects, even though my stutter is more a blocking thing and it isn’t so bad, a presentation is always hard, fortunately I didn’t have block at all and I was very secure of myself, I think thats the point of all, work in your self-esteem, think about it, we (the stutterers) are very smart, I daresay about the average, I know that is hard to avoid the thinking of stuttering while you’re in a presentation, but the most important thing about your speech, is the message, not the form of say it, eventually with the more and more presentations that you will to produce you will get more and more secure of yourself and you’ll be more comfortable. Sorry for my english btw
