Well stated antibiotics again

2nd try treating this Lyme. I am on clarithromycin 500mg 2x a day. Started on Saturday so probably too soon to say ya or nay! lol So far seems like fatigue is better but don't want to jinx it. Have a coppery taste in mouth, which is a side effect, and today the runs have started. Again not sure if its herx, something I ate, or what. Being on antibiotics really scares me and having the runs. Can even kills you. Wouldn't that be funny?? The shits kill me instead of the lyme ahhahahahah. Ok you have to laugh. Besides what other options are there? No other side effects so far. Really hoping it clears up my face too. Tired of looking like a teen. UGH!!
