The first time I took doxy at 300mg. I wasn't nauseous at all but had bad back pain. Now at 400mg. no back pain but woke up very queasy so my LLMD had me switch to the tabs. He claims they are more easily tolerated. Too early to tell as I took a break and I'm now slowly ramping back up.
I did herx on it a bit as it intensified chills and this malaise feeling I get but nothing so terrible.
The Rifampin is a piece of cake once you get over the bright orange urine shock which takes a few days. I am experiencing rashes and little itchy bumps on my stomach, arms and back but don't have a clue if they're from Bart.
