So very glad to stumble across your post ... I thought I was the only one that couldn't hold onto a flavor for very long ... some days better than others .... hopefully this will get better as it's kind of disappointing when my "favorite" flavor just doesn't taste right .... I've also had the frustration of not being able to capture the taste "at all" of something others say is great. Not only are all our taste buds different, but they do change somewhat drastically day to day. Thanks for the post!
