Hi there - I made a post around 6 weeks ago concerning my brother's symptoms on Doxy and the fact he ended up killing himself. In short, if you experience depression, anxiety or panic attacks on this drug you must inform whatever government body in your country regulates these type of drugs. If your in the US that will be the FDA. If you don't tell them, they don't know there is a problem. For the sake of others, please do this as posting your problems on this site will not make them look into the drug.
