What is the quickest way to ensure you don't get a big head about a raise or promotion? Couple that extra (hopefully deserved, you know who you are!) money with a switch from a traditional to Roth 401k. Not only will the increased salary increase your annual contribution if not already maxed out, but it would convert the extra money you earned, and probably more, to additional taxes you'd pay. This doesn't make sense for everyone by any means, but if you are worried that bringing home more money will just make you waste it and perhaps you've already maxed out your Roth IRA and Traditional 401k, this could be an option that works for you.
I will however point out, that something just feels weird if you couple less take home pay with a promotion as I have done. I 'know' I'm getting a better value, but surely don't feel it.
