I'd urge you to take steps to measure what AdWords is achieving for you before you bail on it.
It might prove to be a poor spend, or it might be producing more value than you thought.
Even if you're not currently tracking conversions, you should be able to figure out what percentage of your overall site traffic comes from AdWords and how much it costs. That will give you a better basis for deciding whether AdWords is worthwhile rather than just what you "feel like".
Keep in mind that seeing ads is one of the things that sends people to organic search for products, so watch for evidence of synergy between ads and SEO.
