Worth it to get speech therapy when I don't stutter with therapists?

Worth it to get speech therapy when I don't stutter with therapists? I've worked with two different speech therapists for multiple sessions each. I stuttered zero times with either. In general, I don't stutter with therapists or other health professionals. In everyday life, my stutter varies significantly. It can get bad when I haven't slept well. It's not necessarily noticeable in most situations, but there's often a lot that I don't say due to the stutter. It was quite bad in high school - I'm now in my late twenties - but now is somewhat manageable. Is there anyone else here in a similar situation?
