I have a speaking job that demands me to talk on phone while at work. But my voice seems changed over a year or so. I have been a smoker for 4 years now used marijuana everyday and also used to consume alcohol and hard drugs like coca*ne too. I left it all a few months back. Now I don't know whether it's all related but I get problems in remembering right word to speak at right times. Walking disbalance, and feeling of something constantly stuck in throat..specially after smoking cigarette now.
