RESULTS	However , there were some tendencies to positive differences between Asp Mg versus placebo on the following : 1 ) prolonged delay of BZD use if reintake ( 30 days vs 20 days , p [ log-rank ] = 0.5 ) ; 2 ) reduction of withdrawal intensity : 11 % of important difficulties during BZD cessation versus 23 % with placebo ( p = 0.2 ) and on Benzodiazepine Withdrawal Symptoms Questionnaire ( BWSQ ) ( final score 4.0 vs 4.8 , p = 0.10 ) ; 3 ) lower modification of anxiety during BZD tapering and discontinuation ( rate of increase on HAM-A between d30-d90 of 6 % vs 23 % in placebo group , p = 0.10 ) .\
