Landed a job interview

Landed a job interview Hello, recently I’ve landed a job interview for a job that I’ve always dreamed of as a child. I do not want to screw this up as it’s probably a once in a life time opportunity. It is a group interview and I would like to be able to converse with confidence. My interview is next week and I’m looking for short term solutions. I’m the type of stutterer that experiences blocks. I am thinking of going to my local GP and ask for a short term medication that would help me be more fluent than I already am. What are the odds of me getting prescribed a short term medication? Or will the GP refer me to a specialist for therapy instead? Also, any Off the counter drugs that I can get my hands on? Thank you 🙏
