STUTTER HELP

STUTTER HELP I go through most of everyday life absolutely fine. Day to day there is little evidence of a stutter when I talk. There are however two main times when it rears its ugly stuttering head: 1.) When I've had a drink. No matter how small - even after one pint. It doesn't matter how drunk I am or how much I've had, I always stutter when I've consumed alcohol. 2.) when at work speaking on the phone to clients. Again, this only ever happens when talking to clients, not when in chatting to colleagues etc. Can someone please help me and give me an effective treatment for a stutter? Thanks
