Yes, currently I'm experiencing the same ordeal. I ate out for Mother's Day and have been sick since that midnight. I started out feeling nauseous and having my first liquid BM that night. The next morning, Monday, I puked once and proceeded to go to the bathroom probably five times over the course of 3 hours.
I drank two 20oz of coconut water for electrolytes and rehydration throughout the day. I ate 3 pieces of pizza at 10 p.m., thinking the worst was over, only to lay around for a couple hours feeling flike I was going to puke again--but to no avail.
Tuesday I ate a banana/nut/cinnamon/whey smoothie for breakfast and waited a half hour before deciding to brave the day at work. I made it through without any incidents, though I only ate one egg and one Kombucha w/chia seed and was completely drained of energy. After work, I had a Garden of Life meal replacement shake and took a food-based multivitamin. Later that night, I tried to eat another couple pieces of pizza and felt nauseated again. No BMs all day, not particularly hungry, hardly drank a liter of water all day--kind of weird for me.
Stayed home today, Wednesday, and had a watery BM early on which made me decide to stay home. I was on the fence as to whether or not see a doctor. Mid-afternoon, I had a cramping pain subsided by a surprisingly solid, voluminous BM. Since then, I've eaten a sub sandwich and haven't experienced any nausea.
In retrospect, I'm wondering if I had an obstruction of sorts that caused the pain, resultant of the food poisoning. I'm pretty sure I had food poisoning because a sibling of mine--non-Crohnnie--experienced some minor symptoms from the same sketchy restaurant that night (Ground Round--hardly a higher rung than a Denny's on my ladder).
Looking back, I should have only drank my foods and am planning on picking up some 100% vege/carrot/fruit juices tomorrow to let my bowels rest.
Sorry for hijacking your thread, I just wanted to make a record of my experience for me to remember. I've had food poisoning twice before and had about the same symptoms described above only minus the painful, crampy, possible Crohn's aggravation. Both of those times, I recovered in a little over a day and a half which makes me wonder three days later...
