It might be.

I felt this same way all my life, until 6-months ago, when I found a flavored sugar free mix I actually liked.

I returned from vacation in Mexico, where I was drinking Coke with sugar. When I returned home, regular Coke, made with Corn Syrup in the U.S., tasted off. I decided to take the opportunity to stop drinking it.

I tried dozens of low calorie drink mixes and found one I could tolerate. I did some research and all things pointed to that being healthier than my Coke habit.

My tastes have changed again since starting this, but I don’t drink Coke anymore.

One thing that might have helped was drinking aspartame in my coffee, where its aftertaste is harder to detect.

I should mention the only good side effect I’ve had is a little less bloating, probably a result of avoiding carbonation. I haven’t lost any weight by the change. It’s also much easier to make a diet work when I’m not consuming 800 calories from Coke everyday.
