Disclaimer: I'm not a doctor, and I don't want a medical answer, I'm just looking for experiences, I have an appointment with my doctor in order to discuss this, I want to hear some experiences in the meantime. 

I use Xanax to treat my anxiety, which was great when I had frequent panic attacks, as it is fast acting and intense, but now I don't have panic attacks that often but the generalized anxiety got worse. 

Xanax isn't helping, it usually just calms me down for  an hour or two, but then I can feel the anxiety creeping up slowly. 

What's your experience? Do diazepam and lorazepam have the same effect or are they more lasting?
