Nervousness can always increase the issue of stuttering In many situations the person may feel that he is stuttering less when he is relaxed In homoeopathy there are medicines which can help you get over this issue and counselling would also help you

Dear It may not always be the case that individual stammers because they suffer from communication disorder . Sometimes people stammer only under stressful situations or when they are more conscious of speaking or being watched as in public speaking or delivering presentations or having an interview. I would like to explain that Alcohol takes away inhibitions , that's why social anxiety or self-consciousness doesn't comes into play. Overall , looking at your complaints I strongly recommend you to see a good counselling psychologist for proper assessment and treatment . Stay blessed !
