Bro that's not a solution to your speech over time the effects will change and bruh you stutter out even the more. ask me how I know.... Trust me when I tell you this if you set your mind to believe this every time that you are in a social environment you will feel the need to have coke around. After a while your confidence will be dependent on a bag of coke... Face it and except yourself as you are you can mask your problems for so long before it all blow up.. Hopefully you see this
