Presentation tomorrow for job interview, nerves make it worse!

Presentation tomorrow for job interview, nerves make it worse! Hi everyone, 24 year old long-time stammerer here, have to say i love this sub, so supportive. Moving on, I am an occasional stutterer, but when the occasion strikes its always a block. A big invisible block that I just can't get around. These tend to happen more when I get nervous or edgy, I have a really important presentation to give tomorrow, for a job that I really want and I've prepared extensively, but the nerves are beginning to kick in now, and with them come the dreaded blocks. So does anyone here have any friendly advice on how to calm the nerves, and also what to do in case the blocks hit at an important point in the presentation? Cheers :)
