Hey Bri, Yes, Doxycycline is available in the USA; and it is indeed suggested by the CDD; they sent me the paper work;
This is what I would suggest; you can either take it while you are on the first drug therapy; or if the first drug therapy does not work, take the second line and doxycycline. It is taken twice, like Nitz./alinia. You do not take it with second meal; and it is only 50mg.
Like Coralreef, you can order it through medmex.com and canadianpharamcy.com.
Also, please be sure to post your your daily results with the first therapy and mention the drugs for the sake of others. I wish you luck with this, even though I opted to take the second line therapy. WHich I will do soon. I cannot wait to see if I will be one of the lucky ones.
Can you briefly tell us your symptoms; specifically? In the post?
