Hey there,
I have been taking Doxy now for almost 10 days for Erlichia. (a form of lyme disease) It is a strong drug! I take 100mg twice a day. I get terrible diarrhea, stomach cramps, and nausea. Starting yesterday after being on it for nine days I started getting really bad heartburn, indigestion. I only got heartburn when I was pregnant so I know it's the Doxy. I didn't eat anything out of the ordinary, It kept me up all last night. Thank god tomorrow I take my last pill. I read a lot of posts and feel so sorry for the people having panic attacks and depression. It really makes it difficult for us to take something that is suppose to make us better, but can is actually making us feel sicker!!
