If you were represented by an attorney at the trial, you should probably consult with a malpractice attorney. That is on additional avenue for recovery other than the once suggested by my peers.
You are stuck with your judge. It is possible that a motion for a new trial could be successful if you have new evidence. This needs to be filed within 10 days of the notice of entry of the order. Otherwise you have 6 months to move to set it aside the decree based upon fraud. You did not say what his income is so it is impossible to know how offensive 500.00 per month is. Alimony is always modifiable.
If you have completed the divorce then there will be no more arguments unless there is an appeal or motion to amend or vacate (both rare) that is approved.

You cannot get a new trial, and you cannot get a new judge. An appeal would likley not be successful. It sounds as if you were not ready for trial, as you were not ready to rebut your husband's lies. It is quite normal for people to attempt lies in the courtroom to achieve an advantage. You have to be ready for that, and have the evidence to prove the lies -- or, preferably, have the evidence that proves the truth. Nevada is a community property state, so whether or not he spent his paycheck or used credit cards is irrelevant. The Judge can only divide the community property proven to be in existence at the time of divorce. As the other attorney's have opined, you may have something you can bring a motion on, but my guess is that such is a slim chance. You absolutely need to speak to your attorney about this and what options you have.
