My doctor prescribed doxycycline for stage one of lyme disease just a few days back. Since taking the medication, (100mg twice daily), I have experienced nausea.. most prominent with the morning dose. What surprised me most was when I read the e-mail from another individual who noted that they feel cold all the time, although the temperature outside is warm. Prior to taking the doxycycline, I was running a low temp of just over 100. My temperatures are back to the more normal range now but, I have been freezing and wondering what has been going on!! Perhaps, yet another side effect of doxycycline????
