I look to benzodiazepines because I have failed to respond to SSRI's and MAOI's for anxiety and feel strongly that I would like to play by the rules rather than try other less recognised treatment that have been used with some success i.e.Gabapentin. Benzodiazepines, arguably, are second line therapy. I havent taken the plunge towards taking a benzodiazepine daily because they bother me-They completely block my ability to think clearly. I couldnt even read a book the other day and take any of it in. Yet by giving the pams a trial then I may realise that these intolerable cognitive problems as well as amnesic effects may decrease quite rapidly
Did this concern you guys/gals initially and did you find that when you started taking a benzodiazepine daily these severe cognitve defects and extreme sedation lessened quite quickly.
It was interesting to note what StJames said about a difference between tolerance occuring to the 'high' associated with benzodiazepines and the anxiolytic effects. I wouldnt call the initial benzodiazepine effects a 'high' but they are much more potent and can help with co-morbid depression too. Down the line they may very well worsen it. The anxiolytic effects may last a long time so Ive heard.
