Some folks systems are very sensitive to changes in any domestic water supplies.
Years ago US physicians used to prescribe Doxycicline, taken a few days before and during a trip. Since it is an antibiotic, they decided unnecessary
use of this drug may make you immune to other antibiotics, so they wouldn't prescribe them any longer. They are readily available at any Mexican
pharmacy and will prevent you from getting "The Revenge", just in case you have one of those "overly sensitive systems".
Always good to have them on hand, just in case. |
