Abdominal Cramps -- how quickly did they go away

[nature]

I've been having progressively worse abdominal cramps over the past three days. It's possible I've been exposed to a stomach bug as I ate somewhere dodgy the on the weekend. But also just restarted dexedrine after trying ritalin for a little while. I didn't ramp up but just went back to my original dose. I did not at all have this problem the first time.

For those who have had abdominal cramping -- does it subside after days/weeks and if so how long did it take. I am thinking it may be the dexedrine because it feels more like my abdomen than my stomach. Am visiting my physician (not shrink) tomorrow so will probably get tested for stomach bugs to rule that out.
