In the '60's- 90's anxiety was traditionally treated with what was euphamistically called 'anti-anxiety' drugs - later it was realized that these same drugs whilst calming people were habit forming and people were becoming addicted to them. They were also sometimes used for alcoholism to reduce the anxiety of not being able to 'have a drink' - but it would seem that these drugs were simple 'masking life' giving one a sense of calmness whilst becoming addictive also. The root cause of many anxieties were never discovered or explored thus coming off the drugs the anxiety syndrome re-appeared. This is the case with many psychiatric ailments including the opposite to neurotic conditions and that is psychotic. Remove the drug and the old self re-appears so has anything been cured??
