In my experience at least, "Adderall makes you go to the bathroom" has certainly not held up as true. I've been prescribed Adderall XR 15 mg BID and, If anything, I think it causes my bowel movements to be more formed, solid, and has almost completely ameliorated my abdominal pain. I think it might have something to do with it just making me happier overall and reducing my anxiety/sadness, and also making me more mobile/active. My IBS is/was predominantly abdominal pain and cramping when going to the bathroom, not really true D. In addition, Adderall significantly helps with my tendency to just constantly eat and eat non-stop, which probably plays a huge role in improving symptoms as well.
I'm taking a break from Adderall right now because I'm on summer break from nursing school (with something like Adderall, taking occasional breaks or even "off-days" can be important), and I'm starting to see a recurrance of abdominal pain again. I think the mind-gut connection (things like serotonin, etc) probably has a lot to do with it.
Adderall can pretty significantly dehydrate you, so especially if you have D, make sure you hydrate (drink slightly diluted Gatorade or something).
