Outside of Neurontin and Lyrica, treatment with any other medication besides benzodiazepines have been entirely ineffective for my different anxiety issues (GAD with panic disorder and chronic acute anxiety (I have no clue if the latter is pretty much the same as GAD, so ...), with neurontin only effective when delivered at the dosage of 3600mg in one dose, kind of the same deal with Lyrica, although I can attain mild relief from 300mg twice a day, not just a single high dose. Well, opiods are not prescribed for anxiety relief even with the potential.for exceptional relief, but that is generally beyond irresponsible even if it were last resort.
SSRI's are considered to be less effective than the TCA's and MAOI's, but they are definitely the safer alternative in most cases, due to potential side-effects and drug interactions. It's a little ... unsettling she would be averse to at least providing you a one month supply of say, sixty lower dose benzos PRN. If only to help you along while the possible reduction of anxiety through the AD to take full effect. Just lime Freeside, why wait? The opportunity to have sure-fire reduction of anxiety while awaiting significant clinical response from the AD would have no negative repurcussions, heck benzodiazepines are pretty much the safest medications out there, and it has been extensively shown that benzos carry a low-risk of abuse when one is in genuine need and there could be an INCREASE in energy due to the physical strain excessive anxiety has on one's body.
I suppose that you'll have to wait and see, SSRI's are effective for some, not so much for others, but if you trust her, and her mind is made up, well, bit of of a waiting game.
Personally, I think that benzodiazepines are the way to go. You have a condition in which benzodiazepines are usually (through my extensive time spent with schizophrenics) a given, and if prone to panic attacks and violent outbursts, the too sedated sounda very much like a feeble excuse. Im not somebody who has psychosis and while a lot of speculation has gone about if I am autistic (including an aspie telling me that I display significant symptoms of aspergers, a person that dealt with me all of the time), so my overly long opinion is what it is, but to try you out on a safe medication that could curb a potential disaster, well, I might not be alive if not for benzodiazepine treatmeny. Good luck. a me.
