Everybody's different. I'm prescribed 900mg Gabapentin per day for social and generalized anxiety (as well as just an all around mood stabilizer). It works pretty well, especially when you first start taking it. I'm also prescribed 1mg Clonazepam per evening mostly for GAD, stress, insomnia, back pain, etc. It also works very well at controlling in-the-moment anxiety, but long term use will definitely heighten your baseline anxiety levels. This is a combo that I've been on for a while (several years) and seems to be working well for me.
To all those saying not even to consider benzos - some people really do benefit from them if they're used responsibly. I may be quite in the minority here, but I treat it as a medication and take 1mg per night exactly as directed and never abuse it. I also take days off every two weeks or so, where i'll only take half or none of my medication. This way it maintains its effectiveness.
Beware the 'benzo trap' - constantly increasing the dose. This is what gets a lot of people in trouble. At 1mg Klonopin per day, I can go one night without it and be fine. People who take 6-10mg Klonopin per day, bless their hearts, absolutely cannot go a day without it, or they'll experience some terrible effects. I'm not sure where you cross the tolerance-dependency-addiction threshold, but long story short if you do go the benzo route, tread lightly. Cold turkey w/d from a high dose habit is definitely one of the most terrifying things I've ever been through (my benzo dose wasn't always this low.)
Also consider meditation, exercise, eating well and sleeping well. All these things really do help. But if you feel that benzos are something that you need, talk to you doctor about it. You'll probably have to try several other things first. Just bite the bullet and try them, the goal is to become more mentally stable, not to get high. But, as I've said countless times and will say again: it is much better to have a legitimate benzo prescription overseen by a legitimate practicioner of medicine, than it is to be an alcoholic or to be addicted to 'RC' benzos.
EDIT: To those who ask "aren't you retarded from taking benzos every day for years?" Actually I just made Honor Roll (GPA 3.6) at a reputable state University studying mechanical engineering, so no, I do not think using benzos has made me retarded.
