"this medication at 50mg wasn&#039;t working well for my insomnia.  it worked sometimes but was that just fatigue from a sleepless night before.  my md increased to 100 and i started to get mean and sometimes violent with my spouse.  i did not take it on a regular basis because it gave me really bad the dry mouth.  i do not take it anymore because of the hostility.  i have read through all the threads and only 1 other person had that effect.  maybe it is because i am on lexapro for depression.  he switched me to xanax which works but do not like it because it is easily addicting.
