My friend claimed that his tolerance to benzos didn't increase, I thought he was mistaken. Recently, I checked up on benzos in Merck, it said that its possible not to build up a tolerance, in certain people at certain dosages. I'm currently taking Risperdal for anxiety, but prefer the effects of benzos. The only reason I'm not taking them is that I don't want to end up needing to take more, and more. Is there some way to know if I won't develop a tolerance to them, beforehand?
