Can you elaborate on affect changes? I had a similar regimen and experienced a weird sense of mental clarity and sociability for a couple of weeks after. Never have figured out what the mechanism was.
Positive affect changes are a noted possible side effect. The mechanism is unknown. Some scientists believe it's the direct action of the drug on the brain, but others believe it has something to do with altering the natural intestinal flora and a vague "gut-brain connection". It's an area of research waiting to be tackled.
I wasn't going to complain about feeling better than normal, only a little disappointed after the scrip ran out.
I had hypothesized that the antibiotics were either giving my immune system a boost which was tamping down some underlying inflammation somewhere, or were helping fight some intestinal flora that normally cause some subtle mood effects that I wouldn’t normally notice until it was absent. But I was never able to find anything online to pin it down one way or the other.
