I'm in somewhat of a similar situation right now. I started a new job in software a couple of months ago, and my stutter was hardly noticeable then. In the past month or so, it's gotten significantly worse, with a ton of more blocks. It's pretty shitty, because I'm constantly in meetings and discussions where I need to talk. Right now, I'm trying a couple of nootropics (see /r/nootropics) but those don't have much effect. I am hoping to see an SLP about it and hopefully their exercises will help.
