As someone living in Mexico, I am always frustrated when reading horror stories from people in the USA about medicines. I have always been 100% willing to help getting any required medicines if needed.
And here I am today in the USA (visiting for 1 week of work), with what appears to be a stomach infection, and I'll have to just survive it maybe with Pepto, until I go back to Mexico, or otherwise pay a lot of money to see a GP to give me a receipt for a something that will cost me $6 USD back in Mexico ( https://www.angloinfo.com/blogs/mexico/mexico-city/more-adve... )
