"i have been taking 1 1/2 mg every other night for sleep for the past 3 years. i have tried my other drugs for sleep and ativan is the only one that works consistently. 
because of its addiction potential i take it only every other night.
also i have not had to increase the dosage in 3 years, which i believe is a result of not taking it every night.
it is easier to tolerate my non-ativan night of insomnia when i know i will be sleeping well the next night."
