I am 17 years old and lately when I eat certain foods, they taste very sour. For example, I had some cheese that was just bought and it tasted like it had gone bad. I also had tofu the other night, and that tasted sour as well. I would think that I just have sensitive taste buds, but the odd thing is, I can eat a whole lemons and limes.
I have also notice a weight loss of about five pounds in the past week and I have been extremely tired.
