Night sweats is a common withdrawal symptom for klonopin. If you have been taking klonopin for quite a while and usually take it every day, maybe you are having withdrawal symptoms when you don't take it.

Do you have nights when you don't take klonopin and don't drink alcohol and still have a lot of sweating?

If you normally take klonopin every day, it's still in your bloodstream even if you skip a day. The concentration will be lower, and that can trigger withdrawal symptoms, but it's still present.

Please be careful mixing alcohol with it. I know that's no fun to hear, but it can be very dangerous. I'm saying this based on experience.
