Has anyone experienced anything like this before? I am an older lady - and have drunk coffee with milk for the best part of 45 years. Occasionally, when on a diet, I have tried drinking it black. Yeugh!! Over the last couple of weeks I have been struggling with drinking coffee (i don't drink tea) and blamed the water at work. Then I struggled with it tasting 'off' at home. Eventually I tried it black - and it's great! This happened over the course of about 2 weeks. I haven't gone off milk - I still drink lattes when I'm out and occasionally at home and they are fine. I just find this really weird.
