I just stopped taking klonopin. It's been about a month and a half of not taking any benzos. Just like you, when I first started taking klonopin, it was a lifesaver, then, I needed 10+ mg just to feel relief. It also started making me miserable and flat out crazy while I was on them. If you have sudden panic attacks, I highly suggest taking your doctor up on the xanax idea. Xanax will work wonders for you. But just like any other benzo, or drug for that matter, tolerance WILL develop and you will start needing more for the same effect. The best advice I could possibly give you is to take the benzos when you need them most and not just because you feel like you want a buzz. This is going to be hard though, especially if you're like me and you love the feeling benzos give you. Good luck dude.
