Has klonopin not really work for anyone else?
Sure, it happens. Everyone's biology is a little different.
Also, what should I expect from Ativan? I'm looking for something to really chill me out.
Ativan is a slightly less potent benzodiazepine (BZD) than Klonopin, but it does have the advantage of being a BZD that your brain is used to as it is a natural constituent
of food. Whether this actually increases its effectiveness in your case remains to be seen, however.
Is there a reason why your anxiety is being treated with BZDs and not antidepressants? While they are usually very effective, BZDs can be risky primary anti anxiety drugs because doctors are becoming increasingly reluctant to prescribe them so getting prescriptions may become hard to get in the future. Even if your doctor is happy to do so them s/he could be taken out by the proverbial bus tomorrow and the replacement may not be as willing.
