My gripe is when it is suggested that alcohol is not a drug. E.g.
John Smith was addicted to alcohol and drugs.
Surely it should be alcohol and
other drugs.
If you have not read it already, I think you would find Allen Carr's book on alcohol very interesting as he addresses these points. You can buy it on Amazon and it is called
Allen Carr's Easy Way to Control Alcohol/Stop Drinking (the title depends on whether or not you buy the British or US version; they're essentially the same though).
