What medicine can I take to reduce stuttering and not have side effects in the short term?

What medicine can I take to reduce stuttering and not have side effects in the short term? Hi, I've been analyzing myself and I realized that I have bad days 5 days a month, the rest I'm at tolerable levels of stuttering. Therefore, I would like to eliminate these 5 bad days from my life, and I know that this period is too short for any medicine to cause me problems with side effects. What do you recommend?
