Doxycycline
chlamydia infection
"I found out I had chlamydia 3 days ago. With the doxycycline I've had a really upset tummy but not been sick. My main problem is I'm really aching and do feel like my anxiety level has increased.  I take two 100mg tablets a day.  Thank goodness I only have too take it for 4 more days as I'm taking other medication on top of this I'm not a big tablet taker at all and I've lost my appetite"
