Hi Bellyknot,Yes, I am in the US! (I really loved that question!) I live in the Bay Area. What tincture opium does is slow your system down so you're not constantly running to the bathroom (or just staying there).I started on .6cc's four times a day. It tastes awful so I mix it with diet root beer. Your doctor will need to write the prescription in triplicate (it is a controlled substance). And you'll get plenty of stares trying to fill the prescription.Tincture opium is an old idea so most people have never heard. Which means most pharmacy's don't have it on hand so they'll have to order it for you. I happened to find a great new pharmacy due to this snag!I hope this is helpful!LouLou
