Oh My Goodness, I wish I would have read all these wonderful post before last night. My doctor put me on this horrible medicine. I developed a very bad sore throat and lost my voice for three days. During this time I was so worn out and tired all the time! My doctor said I had a viral infection, I got better and started taking the medicine again, last night. I woke up with a sore throat and tonight after work I am throwing all this medicine away. I don't like all the side affects headache, constant thirst, weight gain, etc.. Bye Bye Singular
