MylesMom08, according to my own experience:
Xanax: worked for 4h and during only 2 days. After this, no more effect at all
Ativan: worked 12h, for 3 days. But with an extra. An abnormal anxiety one day after. This is the worst I tried but at least it was working longer than xanax.
Klonopin: the best of the 3, for me. It works 12h, and never stop to work even weeks after. I felt a little drunk randomly during the first 3 weeks and now I've no side effects at all.
Something to know: xanax is the worst if you want to avoid being addicted. Because of its very very short term action, the addiction risk is high. The more time a benzo works, the less chance you have to get addicted. My opinion is that doctors should forget about xanax and all equivalent very short term benzo.
Side effects: all 3 benzos that I tried, I got very soft side effects, like a bit drowsy, a bit dizzy, feeling like a bit drunk. They can go away with time, or not. But I think most people don't even have any side effects with benzos.
Kryztle21 is right. A benzo can't cure anxiety, is just bluff your anxiety receptors. Like a pain killer when you have a headache. It doesn't remove the headache, it just block the pain to get to you. It is also true that you have high chance that a benzo stop to work with time. And like my personal experience, it can stop to work very fast! SSRIs do something completely different. They do change what is happening in your brain to be responsible for anxiety and depression. So this is more to be called like a real fix, than a simple anxiety patch. Usually, SSRIs that are working, must be took for a long time to lower the risks to be sick again one day. I.e.: between 6 months and a year. Ask your doctor, he will tell you. And then, some people have their problem fixed forever and can stop the SSRI. Some will get their illness back and those should try to take the SSRI longer, or try another.
I don't like SSRIs me too. I had bad experiences. But I think it worth it. You don't know, maybe one is perfect for you. If you don't try, you can't know. I know people that only take benzos. Since it works all the time, and the person is satisfied with this result, some doctors will say that there is no problem to continue. Some will argue that they are dependent. Some will say, ok you're dependent but what's the problem? If you live freely and can pay it, go for it.
Personally I don't feel at ease to live on benzos. I prefer a real fix. But it's me. Now that you know how things work, you can decide by yourself. Good luck.
