Hi expongo291, I totally understand how you feel. As a fellow Brit, I feel the options available are very limited, a part of the reason why I feel I fail so often, as a lack of support. I have been to the doctor numerous times and each time the option has been a self referral and only available with the local Drink and Drugs service during normal working hours. Alternatively there is AA (which isnt for me).
As mentioned above, this forum is fantastic with a wealth of experience being shared and information.
