I had an interesting thing, too. Stuttered from the age of 5, became totally fluent 5 years ago, and started very covertly 8 months ago, scaring myself to death that my stutter would fully return. The doctor thinks a medication I take has done this and I'll DC it and report to him. BTW, my stuttering ended 5 years ago while taking Abilify. Although a side effect caused me to stop it after 8 months 5 years ago, nevertheless I remained fluent until 8 months ago. Now only mild, covert stuttering. Who knows why?
