Coffee consumption and stuttering

If I consume coffee, it increases stuttering with vocal blocks mainly. The vocal blocks mainly happen with starting word. It is more pronounced when demanded in situations such as attendance roll call, saying names in turns and giving report in turns. The vocal blocks cause long pause before I start the word. When tea is consumed, this effect is markedly low. However, consumption of tea is not producing fluent speech also.

Effect of Omega-3 fatty acids

I was taking 2 capsules of mega-3 from Dr Reddy's Laboratories (Each softgel capsule contains Eicasopentaenoic acid - 180 mg and Docosahexaenoic acid - 120 mg) in the night after dinner. It used to give somewhat better sleep in the night than ashwagandha. The next morning, I had stuttering issues such as repetition of words, smaller vocal blocks and stuttering on certain words and a bit anxious. When I skipped the dose one night, the stuttering was markedly less next day with less repetition of words and less vocal blocks. It appears that omega-3 fatty acids increase dopamine in the speech circuit area. Apart from stuttering effects, it improved the mood and motivation a little.  

Effects of Ashwagandha

I took ashwagandha tablet (Himalaya) containing 250 mg of Ashwagandha extract in the night after dinner. After few doses, it appeared to have reduced serotonin and dopamine as evidenced by lowered the mood, motivation and initiative. It appeared to have GABA mimicking effect. However, it was stimulatory and did not give me deep sleep. The next day I was not able to focus and concentrate on work. Also, I felt short of breath. While I was climbing stairs and walking uphill, I felt short of breath. However, while speaking, not much of shortness of breath was observed. I could start the sentence easily and maintain the conversation which was slow. An interesting improvement was observed. If one night's dose was skipped, the speech was more fluent and no shortness of breath next day. It appears that GABA inhibits dopamine and serotonin and ashwagandha enhances GABA tone.
