Adults who develop stuttering or stammering at an early age but weren't able to get the necessary therapy to properly treat their condition are the ones who often face the challenge of learning to accept their stammering without any feelings of insecurity or inferiority.

While it greatly relieves an adult's emotions when one accepts his or her stuttering condition, there is no harm in searching for a possible cure. However, there has been no reported one cure that works for all persons. This is because any two individuals who stutter may have the same outward manifestations, but the factors that trigger the stuttering and the response to it (physical and emotional) can be very different.

You may be able to find a cure that will work for your case and be able to stop your stuttering, but usually, the "cure" consists of techniques which are very helpful but require ongoing practice for you to maintain your "cured state". This is different from actually being completely healed.

Still, it does no harm in trying to get speech therapy again (especially now that there have been great changes in technology and in the techniques used for adults who stutter). Look as well on what other reliable sources would have to offer, as there is always a strong probability that something can be gained from trying anything, and even everything.

But make your choice an informed one. And have the perspective that while you're in search of a cure, you are able to accept your stuttering and are taking the appropriate steps in managing it well.
