Dicyclomine
"Well I have taken many hard drugs in my day! You name it I probably did it! I am not bragging believe me! When you finally grow up, Your stories of drug use and parties turn to shame! And then you wonder how you could have ever been that stupid! But I need to add my history of drug use to make my point here. I have used heroin and many other varieties of opiates. And then finally I used methadone to get off the opiate drugs, Anyway, I was prescribed Dicyclomine 20mg for IBS. And I can honestly say Dicyclomine knocks me on my behind! And it feels very similar to opiates, (At'least for me anyway), (Other people and events and circumstances may vary!) It has helped very well with my IBS. So please people! Be careful if you take this drug."
