Does anyone here find speech therapy actually useful?

Does anyone here find speech therapy actually useful? I did 5 years of speech therapy in elementary school (where thankfully it was free). I don't remember a whole lot of what happened, but it seemed to me that most of the work the therapist had me do was more geared towards children with general fluency or pronunciation difficulty as opposed to an actual stutter. I don't remember it helping at all. In high school I went to a handful of sessions with another speech therapy. Ended up having to stop going because it wasn't covered well under my health insurance and my parents couldn't afford to keep sending me. This therapist did try to help me with my specific stutter, but not much came of it. I felt like a lot of it was trying to learn "tricks" to help control my speech. I only ever found one of those tricks useful, and it involves clicking my tongue on the roof of my mouth to try to force a sound. Sometimes it works, but when it doesn't I'm left there with an open mouth making embarrassing clicking sounds on my mouth. A lot of what she had me practice was just trying to be more confident in my speech, for example she'd have me walk up to random people in the hospital asking simple questions. But in most of my experience, I didn't really mind much of it useful. It seemed like a total waste a lot of the time. I'd be interested in hearing other peoples stories about speech therapy. What was your experience?
