I was in Mumbai last year, and then Mumbai and Uttar Pradesh in late March / early April. I got sicker than a dog from the sanitation or lack thereof, and I have a pretty robust constitution and immune system and know enough not to drink the water or eat street food. Trust me, take Imodium and maybe even get an antibiotic to have on hand. Honestly, I doubt I’ll ever go back to India. The last time I was that ill was having the flu (the real flu) about 10 years ago.
