hi, I returned on 12/23 from 10 days in Morocco. I came back with something respiratory. The cough is getting better, but still present and still have nasal congestion, but is now clear. Do I need to do anything further or just let it work its way out. Also, on our last day, I ate at a local fish market and had salad. My digestive system is a bit off, not like when I got sick in India, but off. Is there anything over the counter to help me work it out?
