Switch to unsweetened, unsalted peanut butter. It's amazing - after 2 weeks I stopped noticing the difference. The amount of sugar in most peanut butter is absurd.
Once you kick the sugar taste, oh wow do you realize its got a much more interesting and involved flavor.
It probably does. Colloquially when one says peanut butter, people think of Jiff, which can be best described as a disgusting peanut-flavored spread product. Go with natural peanut butter (i.e. where the only ingredient is peanuts and it must be stirred) and you're all good.
